By how many newtons does the weight of a 100-kg person change when he goes from sea level to an altitude of 5000 m? (The mean radius of the Earth is 6.38 × 10⁶ m.) A)0.6 N B)1.6 N C)2.6 N D)3.6 N E)5.2 N

Question

The weight change can be calculated using the formula for gravitational force: F = G * (m1 * m2) / r^2. The change in weight is due to the change in distance from the Earth's center. At 5000 m altitude, the distance from the Earth's center is 6.38 × 10^6 m + 5000 m. The difference in gravitational force at sea level and at 5000 m is approximately 1.6 N.
