A force varies with time and traces a sine curve. The peak value of force is `F_(0)`. The average force is given by

A

`F _(0)`

B

`sqrt (F _(0))`

C

`sqrt2 F_(0)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
Aveage force `= (int F dt )/( t ) = ("Area enclosed by F -t graph")/(t) =` zero
Remember that average of sin or cos curve over a full cycle is always zero.
