Question

Four point charges, each equal to q = 4 uC, are held
at the corners of a square ABCD of side a = 10 cm.
.
Find the magnitude and sign of a charge Q placed at
the centre of the square so that the system of charges
is in equilibrium.​

Answer 1

Answer:

lets celebrate

Explanation:

our point charges, each equal to q = 4 uC, are held

at the corners of a square ABCD of side a = 10 cm.

.

Find the magnitude and sign of a charge Q placed at

the centre of the square so that the system of charges

is in equilibrium.​

Answer 2

Explanation:

Since all the corners of the square have the same magnitude of 4μC to maintain the equilibrium of the system.

F A +F B +F C +F D = 0

For that Q can be any magnitude and sign as the system is symmetrically balanced.

That's is all right
