Chapter 16, Problem 15P

To determine

To Find: The magnitude and direction of the force on each charge.

Explanation of Solution

Given:

There four charges placed at corners of a square having side $0.100\text{m}$ .

Formula used:

Coulomb’s force:

  $F=k\frac{qq\text{'}}{d^2}$

Here, k is the coulomb’s constant, q and q’ are the charges and d is the distance between them.

Calculation:

Let the magnitude of charge be represented by q and side of the square be l.

  

Force on A due to other charges B, C and D is:

Force on B due to other charges A, C and D is:

Force on C due to other charges A, B, and D is:

Force on D due to other charges A, B, and C is:
