object A exerts a gravitational force of magnitude 8.2 x 10^10 N on object B. determine the magnitude of the gravitational force if, simultaneously, the separation distance is tripled, mA increased by 4 times and m8 is halved. explain your reasons and show all calculations.

the product of masses is 4*1/2 or twice. Separatdion is tripled, so Force is 1/9
new force= old force* 2/9
