Two balls of mass m and 2m are attached with strings of length 2L and L respectively. They are released from horizontal position. Find ratio of tensions in the string when the acceleration of both is only in vertical direction :

If a simple pendulum of mass m is released from a horizontal position, find the tension in the string as a function of the angle theta with the horizontal.

A simple pendulam of length .l. carries a bob of mass .m.. The bob is released from horizontal position. The tension in the string at t he lowest point would be

A particle of mass m is attached to a string of length L and given velocity sqrt(10gL) in the horizontal direction at the lowest point. Find tension in the string when the particle is at (i) lowest position (ii) highest position,

A particle of mass m is attached to a string of length L and given velocity sqrt(10hL) in the horizontal direction at the lowest point. Find tension in the string when the particle is at (a) (i) lowest position (ii) highest position, (b) when the string makes an angle 60^(@) with (i) lower vertical and (ii) upper vertical.

A particle of mass m is tied to a string of length L and whirled into a horizontal plan. If tension in the string is T then the speed of the particle will be :

A particle of mass m is tied to a string of length L and whirled into a horizontal plan. If tension in the string is T then the speed of the particle will be :

Two particles of masses m_1 and m_2 are connected to a string and the system is rotated in a horizontal plane with 'P' as center. The ratio of tension in the two parts of string is
