Torque produces accelerations, I see no acceleration in the description. No torque.
There is a force toward the center (centripetal force).
I don't know which way the ball is rotating,(clockwise, or counter clockwise), so direction of angular mometnum is unknown
A ball (mass = 250 g) on the end of an ideal string is moving in circular motion as a conical pendulum. The length L of the string is 1.92 m and the angle with the vertical is 37 degrees.
A) What is the magnitude of the torque (N m) and direction (from the listed answers) of the torque exerted on the ball about the center of the circle of motion?
B) What is the magnitude of the angular momentum (kg m^2/s) and direction (from the listed answers) of the ball about the center of the cirlce of motion?
