Two points charge of 4\mu C and 2\mu C are placed at theopposite corners of a rectangle. What is the potential difference Va- Vb

Explanation:

From the question we are told that

Two points charge of 4\mu C and 2\mu C

Generally we find the  Va and Vb individually to find there difference

Given a rectangle with two equal sides each,Assume lengths for bot sides

Length L=0.3

Breath B=0.4

Diagonal D=

at  opposite sides

Mathematically Va can represented as

Mathematically Vb is  represented as

Therefore

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
