Q1. On earth, two parts of a space probe weigh 14000 N and 3500 N. These parts are separated by the center-to-center distance of 8m and may be treated as uniform spherical objects. Find out the magnitude of the gravitational force that each part exerts on the other out in space, far from any other objects.

Q2. The field just outside a 3.60cm radius metal ball is 2.95 × 10^2 N/C and points toward the ball. What charge resides on the ball?
