Two charges of 6 C and -3 C are positioned on a line at points 7 and 2 , respectively. What is the net force on a charge of -1 C at -2 ?
1 Answer
Explanation:
Consider the figure. Let the charges
Let the positions at which charges are placed be in the units of meters.
Let
From figure
Let
From figure
Let
This force is attractive and is towards charge
Let
This force is repulsive and is towards charge
The total force or net force on charge
Since the above two forces
Let
Since The larger force
Therefore the force
