Answer #1

Solution;

diameter ,d= 2 cm

Distance between two space = 6.10 cm

Mid point from both sides distance , r

Now two charges are

Case 1:

The electric field from q​​​​​​1 charge at mid point is

And the electric field from q​​​​​​2 charge at mid point is

This sign means the electric field is positive to negative

The total electric field is E,

ANSWER = 323731 N
