Two stones of masses m and 2m are whirled in horizontal circle as shown in figure. Then T1T2 is(T1 & T2 are tensions in the string as indicated in figure)

Two stones of masses m and 2m are whirled in horizontal circle as shown in figure. Then T1T2 is(T1 & T2 are tensions in the string as indicated in figure)

A stone of mass 0.5 kg is attached to a string of length 2 m and is whirled in a horizontal circle. If the string can withstand a tension of 9 N, the maximum velocity with which the stone can be whirled is :A 6 ms–1 B 8 ms–1 C 4 ms–1 D 12 ms–1

From the top of a tower, a stone is thrown up. It reaches the ground in time t1. A secondstone thrown down with the same speed reaches the ground in time t2. A third stonereleased from rest reaches the ground in time t3. Then :(1) t3=2tt21(2) t3=21tt(3)213t1t1t

Two particles of massesm1 andm2 are placed at a distancer. The ratio of gravitational force on massm1 due tomassm2 and on massm2 due to massm1

A stone is allowed to fall from the top of a tower 100 m high and at the same time another stone is projected vertically upwards from the ground with a velocity of 25 m/s. Calculate when and where the two stones will meet.
