Question

the radius of venus's orbit is 0.72 times that of earth's orbit. how much stronger is the sun's gravitational field at Venus than at earth

Answer 1

Answer #1

given

radius of Venus R_V = 0.72 R_E

G = 6.67 x 10^-11 N-m²/kg²

using equation

g = G M / R²

g 1 / R²

g_V / g_E = R_E² / 0.72² x R_E²

g_V / g_E = 1 / 0.72²

g_V = 1.929 g_E

1.929 times stronger
