there are two point charges A and B (10 MC each ) and are 10 cm apart
CONSIDER A POINT POSITIVE CHARGE AT MIDPOINT OF LINE JOINING THE CHARGES
Electric field at centre of line joining the two charge by A = [ k(10 X 106) ] / 0.05 [ REPULSIVE FIELD ]
Electric field at centre of line joining the two charge by B = [ k(10 X 106) ] / 0.05 [ REPULSIVE FIELD ]
AT THE MIDPOINT, BOTH FIELD CANCEL EACH OTHER EFFECT
AND NET ELECTRIC FIELD = 0
{BECOUSE, THEY HAVE IDENTICAL CHARGE AS WELL AS AT SAME DISTANCE }
