Question

Calculate the force on a unit positive charge at p on x axis whose co-ordinates are (x=2m,y=0) due to the following two charges 1. A positive charge of 10−9C situated in air at the origin (X=0,y=0). 2. A negative charge of -2*10−9C situated on X axis(x=1m, y=0

Answer 1

The force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.

Force on the charge

The force on the charge is calculated as follows;

F = k(q1q2)/r²

where;

• r is the distance between the charges = 2 m - 1m = 1m

F = (9 x 10⁹ x 10⁻⁹ x 2 x 10⁻⁹)/(1)²

F = 1.8 x 10⁻⁸ N

Thus, the force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.
