When a ball is taken from the equator to the pole of the earth
  1. a.Its mass increases
  2. b.Both its mass and weight change
  3. c.Its weight increases
  4. d.Its weight decreases

Answer: (C) Its weight increases

Mass is constant regardless of location. However, the Earth is slightly flattened at the poles, making the poles closer to Earth's centre than the equator. Since gravitational acceleration (g) is greater where the radius is smaller, g is higher at the poles. Weight = mg, so weight increases when the ball is moved from the equator to the pole.
