By how many newtons does the weight of a 100-kg person decrease when he goes from sea level to mountain top at an altitude of 5000 m? The mean radius of the earth is 6.38 × 10⁶ m. A)0.60 N B)1.5 N C)2.6 N D)3.6 N E)9.8 N

The weight decrease 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 center of the Earth. At 5000 m, the distance is 6.38 × 10^6 m + 5000 m. The difference in gravitational force at sea level and at 5000 m gives the decrease in weight, which is approximately 1.5 N.
