If masses of two point objects is doubled and distance between them is tripled, then gravitational force of attraction between then will nearly

Answer»

incease by 225%
decrease by 44%
decrease by 56%
increase by 125%

Solution :% change = ` ([G((2m_(1))(2m_(2)))/((3r)^(2))-(Gm_(1)m_(2))/(R^(2))])/(Gm_(1)m_(2)) xx 100`
` = ((4)/(9)-1)/(1) xx 100 = - 56%,`
-ve sign indicates that force of attraction decreases.
