A small sphere of mass `m` suspended by a thread is first taken a side so that the thread forms the right angle with the vertical and then released, then

a small sphere of mass m susopended by a thread is first taken aside so that the thread forms the right angle with the verticle and then realease. (a) find the total acceleration of the sphere and the thread tension as a function of theta , the angle of deflection of the thread from the vertical. (b) Find the angle theta between the thread and the vertical. at the moment when the total acceleration vector of the sphere is directed (i) horizontally (ii)vertically upward and (iii) vertically downward.

A small sphere of mass m is supended by a thread of length l. It is raised upto the height of suspension with thread fully stretched and released. Then, the maximum tension in thread will be

A small sphere of mass m and having charge q is suspended by a light thread.

If a small sphere of mass m and charge q is hanged from a silk thread at an angle theta with the surface of a vertical charged conducting plate, then for equilibrium of sphere the surface charge density of the plate -

A small bob suspended by a thread swings in a vertical plane so that angle made by thread in extreme positions with the vertical is theta=sin^(-1)(4/5) What is the ratio of acceleration of bob in extreme position to its acceleration in lowest position?

A simple pendulum consists of a small sphere of mass m suspended by a thread of length l . the sphere carries a positive charge q . The pendulum is placed in a uniform electric field of strength E directed vertically upwards. With what period will pendulum oscillate if the electrostatic force acting on the sphere is less than the gravitational force ?
