Assertion : Millikan's experiment established that electric charge is quantised.
Reason : From this experiment mass of the electron could not be determined.

A

`(pi)/8(1+sqrt(2))`

B

`(pi)/4(1+sqrt(2))`

C

`(pi)/(8sqrt(2))`

D

`(pi)/(4sqrt(2))`

Text Solution

Verified by Experts

The correct Answer is:
A
`int_(0)^(pi//2) sinx dx=(((pi)/2-0))/4(sin 0+"sin"(pi)/2+2"sin"(pi)/4)`
`=(pi)/4(1+sqrt(2))`
`=(pi)/8(1+sqrt(2))`
