Re: Joint Entrance Screening Test Entrance Exam Question Paper

Here is the list of few questions of Joint Entrance Screening Test exam paper for your idea .

1. Black-body radiation, at temperature Ti fills a volume V. The system expands adiabatically
and reversibly to a volume 8V. The final temperature Tf = xTi, where the factor x is equal to
(a) 0.5 (b) 2.8 (c) 0.25 (d) 1

2. A particle of mass m, constrained to move along the x-axis. The potential energy is given
by, V(x)=a + bx +cx2, where a, b and c are positive constants. If the particle is disturbed
slightly from its equilibrium position, then it follows that
(a) it performs simple harmonic motion with period 2 pÖ(m/2c)
(b) it performs simple harmonic motion with period 2 pÖ(ma/2b2)
(c) it moves with constant velocity
(d) it moves with constant acceleration
