A second charge of equal mass and charge 92 =-58.0 nC is located below the first charge a distance d = 2.00 cm below the first charge as in the figure 3:34 Type here to search

Explanation / Answer

Electrostatic force is given by:

F = kq1q2/r^2

Usig given values:

k = 9*10^9

q1 = 6.82 nC

q2 = 4.02 nC

r = 1.88 m

So,

F = 9*10^9*6.82*10^-9*4.02*10^-9/1.88^2

F = 6.98*10^-8 N

Since both charge are positive, So force will be repulsive
