1What are the dimensions of the Universal Gravitational Constant (G)?

A.[M^-1 L^3 T^-2]

B.[M L^3 T^-2]

C.[M^-1 L^2 T^-2]

D.[M^-1 L^3 T^-1]

Explanation: According to Newton's Law of Gravitation, F = G * m1 * m2 / r^2. Rearranging for G gives G = F * r^2 / (m1 * m2). Substituting the dimensional formulas for Force [M L T^-2], distance [L^2], and mass [M^2], we get [M^-1 L^3 T^-2].

2Which of the following is equivalent to the unit of impulse?

A.Newton-second

B.Joule-second

C.Newton per second

D.Watt-second

Explanation: Impulse is defined as the change in momentum or the product of force and time interval. Its SI unit is the Newton-second (N s), which is equivalent to kg m/s.

3How does the escape velocity of a body from the Earth depend on its mass (m)?

A.It is independent of mass (m^0)

B.It is directly proportional to mass (m^1)

C.It is inversely proportional to mass (m^-1)

D.It is proportional to the square root of mass (m^0.5)

Explanation: The escape velocity formula is v_e = sqrt(2 * G * M / R), where M is the mass of the planet and R is its radius. Since the mass of the body (m) does not appear in this equation, escape velocity is independent of the body's mass.

4Which law of thermodynamics defines the concept of temperature?

A.Zeroth Law

B.First Law

C.Second Law

D.Third Law

Explanation: The Zeroth Law of Thermodynamics states that if two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This law introduces the concept of temperature as a shared state variable.

5What is the electric field strength inside a hollow charged spherical conductor?

A.Zero

B.Directly proportional to the distance from the center

C.Inversely proportional to the distance squared

D.Constant and equal to the value at the surface

Explanation: According to Gauss's Law, the charge enclosed inside a hollow conductor is zero. Therefore, the electrostatic field inside the hollow charged spherical conductor is zero at all interior points.

6How does the electrical resistance of a semiconductor change with an increase in temperature?

A.It decreases

B.It increases

C.It remains unchanged

D.It first increases and then decreases

Explanation: Semiconductors have a negative temperature coefficient of resistance. As temperature increases, more covalent bonds break, releasing charge carriers (electrons and holes), which significantly increases conductivity and decreases resistance.

7Which of the following electromagnetic waves has the highest frequency in the electromagnetic spectrum?

A.Gamma rays

B.X-rays

C.Ultraviolet rays

D.Infrared waves

Explanation: In the electromagnetic spectrum, Gamma rays lie at the extreme end with the shortest wavelength and consequently the highest frequency (above 10^19 Hz) and highest photon energy.

8Under what condition does total internal reflection occur at the interface of two media?

A.Light travels from denser to rarer medium and angle of incidence is greater than critical angle

B.Light travels from rarer to denser medium and angle of incidence is greater than critical angle

C.Light travels from denser to rarer medium and angle of incidence is less than critical angle

D.Light travels from rarer to denser medium and angle of incidence is less than critical angle

Explanation: Total internal reflection (TIR) occurs when a light ray travels from an optically denser medium to an optically rarer medium and the angle of incidence in the denser medium is greater than the critical angle for the pair of media.

9Two nuclei are classified as isotopes if they have which of the following properties?

A.Same atomic number but different mass numbers

B.Same mass number but different atomic numbers

C.Same number of neutrons but different atomic numbers

D.Different atomic numbers and different mass numbers

Explanation: Isotopes are atoms of the same chemical element that have the same atomic number (number of protons) but different mass numbers (due to a different number of neutrons in the nucleus).

10Which of the following are the majority charge carriers in a p-type semiconductor?

A.Holes

B.Free electrons

C.Conduction band electrons

D.Donor ions

Explanation: A p-type semiconductor is created by doping an intrinsic semiconductor with trivalent impurities (such as boron or indium). This introduces a large concentration of vacant covalent states, which behave as positive charge carriers called holes.

JCECE Study Tips from Top Performers

1Refer to the Class 11 and 12 NCERT textbooks for Physics, Chemistry, and Biology, as the questions are directly aligned with the NCERT curriculum.

2Solve numerical problems daily in Physical Chemistry (like equilibrium, chemical kinetics) and Physics (like mechanics, electromagnetism) to improve speed.

3For Mathematics, focus on high-weightage topics like calculus, coordinate geometry, and vectors by practicing standard problems.

4Take mock exams using physical OMR sheets to learn to shade circles quickly and accurately without double marking.

5Track your mistakes in practice sets, review the theoretical explanation of each wrong choice, and revise those weak areas regularly.

Frequently Asked Questions

Is there any negative marking in the JCECE Exam?

Yes, there is negative marking in JCECE. For every correct answer, 1 mark is awarded. For every incorrect answer, 0.25 (1/4th) of a mark is deducted from the total score.
