Somebody help with this circular motion question

In summary, circular motion is the movement of an object along a circular path characterized by a constant change in direction but a constant speed. It is different from linear motion in that it involves movement along a curved path and has constantly changing velocity and acceleration. The centripetal force is necessary to maintain circular motion and is directed towards the center of the circle. It is related to circular motion as it is essential for the object to continue moving in a circular path. The centripetal force can be calculated using the formulas F = mv^2/r or F = mrω^2.

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

What have you done so far?

Hint: Consider the radial and tangential components of the acceleration.
 

1. What is circular motion?

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.

2. How is circular motion different from linear motion?

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.

3. What is the centripetal force in circular motion?

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.

4. How is centripetal force related to circular 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.

5. How can I calculate the centripetal force?

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.
