Question

A car on a level road turns a quarter circle ccw. You learned in Chapter 8 that static friction causes the centripetal acceleration. The work done by static friction is:_________.
A. Positive
B. Equal too
C. Negative

Answer 1

Answer:

Zero

Explanation:

As we know that the force and the motion direction should always be perpendicular to each other due to which the work is done by static friction be zero

Therefore

F.dcos(theta) = F.d cos(90) = 0

Hence, the work done by static friction is zero

Therefore the same is to be considered
