The length, breadth and thickness of a strip are `(10.0 pm 0.1) cm.(1.00 pm 0.01) cm` and `(0.100 pm 0.001) cm` respectively. The most probable error in its volume will be

Text Solution

Verified by Experts

The correct Answer is:
zero
Charge on outer plates `=(sigmaA+2sigmaA-sigmaA)/2=sigmaA`
Charge distribution
Field at A: `E_(A)=0`
Field at B :
`E_(B)=(2sigma)/epsilon_(0) :. E_(A)/E_(B)=0`
