A bob of mass `m` suspended by a light inextensible string of length 'l' from a fixed point. The bob is given a speed of `sqrt(6gl)`. Find the tension in the string when string deflects through an angle `120^@` from the vertical.

A particle is suspended by a light vertical inelastic string of length 1 from a fixed support. At its equilbrium position it is projected horizontally with a speed sqrt(6 g l) . Find the ratio of the tension in the string in its horizontal position to that in the string when the particle is vertically above the point of support.

A bob of mass m suspended by a light string of length L is whirled into a vertical circle as shown in the figure. What will be the trajectory of the particle if the string is cut at Point B?

A bob of mass m suspended by a light string of length L is whirled into a vertical circle as shown in the figure. What will be the trajectory of the particle if the string is cut at Point X?

A heavy particle hanging from a fixed point by a light inextensible string of length l is projected horizonally with speed sqrt(gl) . Find the speed of the particle and the inclination of the string to the vertical at the instant of the motion when the tension in the string is equal to the weight of the particle.

A heavy particle hanging from a fixed point by a light inextensible string of length l is projected horizonally with speed sqrt(gl) . Find the speed of the particle and the inclination of the string to the vertical at the instant of the motion when the tension in the string is equal to the weight of the particle.

A particle of mass m is suspended by a string of length l from a fixed rigid support. Particle is imparted a horizontal velocity u=sqrt(2gl) . Find the angle made by the string with the vertical when the acceleration of the particle is inclined to the string by 45^(@) ?

A heavy particle hanging from a fixed point by a light inextensible string of length l is projected horizontally with speed (gl) . Then the speed of the particle and the inclination of the string to the vertical at the instant of the motion when the tension in the string equal the weight of the particle-
