Question

PartA Does the weight of Curiosity vary ifit makes its way from a valley foor to the top of a tall hil? Explain. No, the gravitational force would remain the same because Curiosity is still on the surface of the planet So its weight would remain the same as well. in accord with the inverse-square law the gravitational force on Curiosity at the higher location is less. So its weight is less at the top of the hill. Submit Provide Feedback Next >

Answer 1

According to Newton�s Gravitational law I = G m_1 m_2 I� = G m m/r^2 = mg Therefore g = G m/r^2 M rightarrow Mass of Earth m rightarrow mass of man F^- 1 = (Gm/R^2) M = mg rightarrow Weight of the earth surface would remain same because radius of earth is not on earth R + radius of earth const on earth surface rightarrow As we on hill station and top hill Radius of each is changing so it�s weight is use at the top of the ball rightarrow F^- 1 = G M/[R + n]^2 m mg Actual weight f person So Mg_app < mg weight will be less at the top pf the hill
