Question

Three charges each of 20 microcoulomb are placed along a straight line successive charges being 2 metre apart as shown in figure calculate the force on the charge on the right end

Answer 1

Answer:

$electric \: force \: ( f )= 9 \div 10 ^{ 9} ((q1 \times q2) \div r ^{2} )$

Explanation:

q1 = q2 = q3 = 20 microcoulo

F = 1.125 × 10^-2 N
