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 ball suspended by a thread swings in a vertical plane so that its acceleration in the extreme position and lowest position are equal. The angle  of thread deflection in the extreme position will be - 2

A ball suspended by a thread swings ia a vertical plane so that its acceleration in the extreme position and lowest position are equal. The angle theta of thread deflection in the extreme position will be

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 plumb bob is hanging from the ceiling of car. If the car move with acceleration a, the angle made by the string with the vertical is

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.

When a particle moves from mean position to extreme position, its velocity and acceleration are in ……………. Direction.

A ball attached to one end of a stringj swings in a vertical plane such that its acceleration at point A (exterme posiuion) is eqal to its acceleration at point B (mean posirion), The angle theta is
