Answer 1

4.

F = k q ( q1/ r1^2 - q2 / r2^2)

F = 9*10^9* 0.3* ( 0.4/ 2^2 - 0.2/ 5^2)

F = 2.484*10^8 N

========

5.

F = 9*10^9* 0.3* ( 0.4 / 2^2 + 0.2/ 5^2)

F = 2.916*10^8 N

========

6.

F = 9*10^9* 0.3*0.4 / (2^2 + 2^2) = 1.35*10^8 N

in component form,

F = -( 1.35 cos 45 i - 1.35 cos 45 j) * 10^8

F = - 10^8 i - 10^8 j

========
