A7.5 nc point charge and a - 2.9 nc point charge are 3.2 cm apart. what is the electric field strength at the midpoint between the two charges

Net electric field,

Explanation:

Given that,

Charge 1,

Charge 2,

distance, d = 3.2 cm = 0.032 m

Electric field due to charge 1 is given by :

Electric field due to charge 2 is given by :

The point charges have opposite charge. So, the net electric field is given by the sum of electric field due to both charges as :

So, the electric field strength at the midpoint between the two charges is 91406.24 N/C. Hence, this is the required solution.
