Two point charges of 8.7×10−6 C, on the left, and −2.7×10−6 C, directly to its right, are separated by 0.071 m. Find the electrostatic force acting on the charge on the left. A force to the right is taken as positive, while one directed to the left is negative.

Answer 1

they will attract, so the force will be to the right.

f=kq1q2/d^2
