A body moves in a circle of radius 5m with a speed of 5m/s square.then...
The correct option is 3- Both A and B are correct.
A- The body moving in a circle with a constant speed of 5 m/s has an acceleration of 5 m/s² towards the center of the circle. This is known as centripetal acceleration and is given by the formula a = v²/r, where v is the velocity and r is the radius.
B- The direction of the acceleration in a circular motion is constantly changing as the body moves around the circle. This is because acceleration is a vector quantity and it always points towards the center of the circle. So, the acceleration varies with direction alone.
Therefore, both statements A and B are correct.

A body moves in a circle of radius 5m with a speed of 5m/s square.then...
*since speed of body is 5m/s²…… acceleration must be different. At a point of starting acceleration and speed can be same but question is stating that body is in momentum.
*since body is moving on circular path, it's direction is varying and hence acceleration must be varying.
*since body is moving on circular path, it's direction is varying and hence acceleration must be varying.
