A light rigid rod is placed on a smooth horizontal surface. Initially the end `A` begins to move vertically upward with constant velocity `v_(0)` and centre of the rod upward with a velocity `v_(0)//2` having downward acceleration `a_(0)//2`, the other end moves downward with

At the initial moment three points A, B and C are on a horizontal straight line at equal distances from one another. Point A begins to move vertically upward with a constant velocity v and point C vertically downward without any initial velocity but with a constant acceleration a. How should point B move vertically for all the three points to be constantly on one straight line. The points begin to move simultaneously.

A bomb explodes in air in two equal fragments. If one of the fragments is moving vertically upwards with velocity v_(0) , then the other fragment is moving-

Time period of a spring pendulum when lift moves downward with constant velocity v is T second. When the lift moves upward with constant acceleration = (g)/(3) , the time period will be

A conducting rod of length 1 is moving on a horizontal smooth surface. Magnetic field in the region is vertically downward and magnitude B_(0) . If centre of mass (COM) of the rod is translating with velocity v_(0) and rod rotates about COM with angular velocity v_(0)//l , then potential difference between points O and A will be
