Answer» Explanation:WEIGHT of the object is given by, W = mg, where g is ACCELERATION due to gravity.and we know as well, acceleration due to gravity is INVERSELY proportional to r² [i.e., g = GM/r² ]so, if earth shrinks to 50% of its real radius. acceleration due to gravity become 4 times of its initial value.then, weight of a body becomes 4 times. i.e. W' = 4mgso, percentage increase = (4mg -mg)/mg × 100 = 300%Thanks!I hope it will HELP you.Good LucK! |
