Question

A charge of 2.65 mC is placed at each corner of a square 0.170 m on a side.

a) Determine the magnitude of the force on each charge

b) Determine the direction of the force on a charge

Thank you

1. along the side of the square outward of the other charge that lies on the side 2. along the line between the charge and the center of the square outward of the center 3. along the line between the charge and the center of the square toward the center 4. along the side of the square toward the other charge that lies on the side

Explanation / Answer

a)
net force acting on each charge, Fnet = 2*k*q^2/L^2 + k*q^2/(2*L^2)

= 2*9*10^9*(2.65*10^-3)^2/0.17^2 + 9*10^9*(2.65*10^-3)^2/(2*0.17^2)

= 5.47*10^6 N

b) 3.along the line between the charge and the center of the square toward the center
