A simple pendulum is oscillating with angular displacement of 90 degrees . For what angle with the vertical the acceleration of bob is directed horizontally ?
Thanks

Circular motion is the movement of an object along a circular path. This type of motion can occur in both natural and man-made systems and is characterized by a constant change in direction but a constant speed.
Circular motion involves the movement of an object along a curved path, while linear motion involves movement in a straight line. In circular motion, the velocity and acceleration of the object are constantly changing due to the changing direction, whereas in linear motion, the velocity and acceleration remain constant.
The centripetal force is the force that keeps an object moving in a circular path. It is always directed towards the center of the circle and is necessary to maintain the object's motion.
Centripetal force is essential for an object to continue moving in a circular path. Without this force, the object would move in a straight line tangent to the circle.
The centripetal force can be calculated using the formula F = mv^2/r, where F is the centripetal force, m is the mass of the object, v is the velocity, and r is the radius of the circular path. Alternatively, it can also be calculated using the formula F = mrω^2, where ω is the angular velocity of the object.
