A body of mass 0.8 kg is whirled uniformlyt at the end of a string 2 m long.If teh string makes 3 revolutins in 1.5 sec,calculate the tension in the string.

Two masses 8 kg and 12 kg are connected at the two ends of a light inextensible string that goes over a frictionless pulley. Find the acceleration of the masses, and the tension in the string when the masses are released.

Two blocks M_1 and M_2 having equal mass are free to move on a horizontal frictionless surface. M_2 is attached to a massless spring as shown in the figure. Initially M_2 is at rest and M_1 is moving towards M_2 with speed v and collides head-on with M_2

Three equal weights of mass 2 kg each are hangning os string passing over a fixed pulley as shown in fig.What is the tension in the string connectig weights B and C? .

Two bodies of masses 10 kg and 20 kg respectively kept on a smooth, horizontal surface are tied to the ends of a light string, a horizontal force F = 600 N is applied to:- A what is the tension in the string?

Mass m_1 moves on a slope making an angle theta with the horizontal and is attached to mass m_2 by a string passing over a frictionless pulley as shown in the figre. The co-efficient of frition between m_1 and the slopping surfaace is mu . Which of the following statements are true?

Two charged particles having charge 5 uC each are joined by an insulating string of length 1 m and the system is placed on a smooth horizontal table. Find the tension in the string.

A block of mass M is places in the top of a biggr block of mass 10 M as shown in fig.All the surfaces are frictionless.The system is released from rest.Find the distance moved by the bigger block at the instant the smaller block reaches the ground. .
