1.	Question 71: If the distance between two masses is increased by a factor of 5, by what factor would the mass of one of them have to be altered to maintain the same gravitational force ? Would this be an increase or decrease in the mass ? Lakhmir Singh Physics Class 9
Answer» MASS of one of them have to be altered by a factor of 25 to maintain the same GRAVITATION force.Because,Force is inversally oroportional to square of distance .As distance increases by 5 times.So , F will decrease by 5^2= 25 times.Hence, mass of any one of the bodies should be increased by 25 times to maintain the same gravitaional force.
