Question

During the course of a turn, an automobile doubles its speed. What change will we observe in centripetal force?

• A. Becomes eight times.
• B. Gets halved.
• C. Becomes four times.
• D. Becomes twice.

Answer 1

The correct option is C

Becomes four times.

Since F _c varies with v ² , an increase in velocity by a factor of two must be accompanied by an increase in centripetal force by a factor of four.
