A body starts from rest at time t = 0, the acceleration time graph is
shown in the figure. The maximum velocity attained by the body
will be

A particle starts sliding down a frictionless inclined plane. If Sn is the distance traveled by it from time t = n - 1 sec to t = n sec, the ratio Sn / Sn+1 is

A wire of length \(l = 6 \pm 0.06\) cm and \(r = 0.5 \pm 0.005\) cm and mass \(m = 0.3 \pm 0.003\) gm. Maximum percentage error in density is

Pressure depends on distance as, \(P = {\alpha \over \beta }\exp \left( { - {{\alpha z} \over {k\theta }}} \right)\), where \(\alpha\), \(\beta\) are constants, z in distance, k is Boltzman's constant and \(\theta\) is temperature. The ...

A particle is acted by a force F = kx, where k is a +ve constant. Its potential energy at x = 0 is zero. Which
curve correctly represents the variation of potential energy of the block with respect to x
