Detailed explanation-1: -1 Answer. Weight of an object is the force with which earth attracts the body. In the given problem your weight will become half of original weight.
Detailed explanation-2: -In fact, without gravity, all matter would fly apart and everything would cease to exist. Gravity is the attractive force between two objects at a fixed distance r. The strength of gravity is proportional to the mass of the two objects and inversely related the distance between them.
Detailed explanation-3: -If the mass will decrease, then gravitational attraction between earth and sun must decrease, and its angular momentum must decrease, which would result in greater orbit of earth and earth being cooler over the time, but instead the temperature of earth is increasing, why is it so?
Detailed explanation-4: -Hence, the correct answer is that If the radius of the earth is reduced to half of its present value, with no change in the mass, the acceleration due to gravity will become Four times to that of the original value which is option B.
