Question

If the central angle of region A in the circle is 7 degrees, what is the expected value of a spin?

a) 7⁰
b) 180⁰
c) 360⁰
d) 0⁰

Answer 1

The angle formed between the vectors of tangential velocity and centripetal force is 90°.

Step-by-step explanation:

The angle formed between the vectors of tangential velocity and centripetal force can be found using the formula:

Angle = arctan(vt/vc)

where vt is the magnitude of the tangential velocity and vc is the magnitude of the centripetal force. Since both vectors are perpendicular to each other, the angle formed between them is 90° (option c).
