Question

A metal sphere of radius 0.1m is charged to a potential 36kv and kept at the corner B of a right angled triangle ABC in which AB=0.4m ,BC=0.5m and amgle B is 90, degree calculate the work required to shift a change of 3microcoulmb from c to corner A of the triangle

Answer 1

Answer :

Hey Mate,

Given,

AB = 0.4m

BC = 0.5m

∠B = 90°

#Figure is attach with this answer.

Q = $\frac{36*10^{3}*0.1}{K}$

KQ = $36*10^{3}*0.1$

$(\frac{KQ}{0.4}-\frac{KQ}{0.5})*3$μ

=> $3600(\frac{0.1}{0.4*0.5} )3*10^{-6}$

=> $\frac{2700*10^{-6}}{0.5}$

=> $5400*10^{-6}$

=> $5.4*10^{-3}J$
