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.

    Consider the gravity equation.

    F=G mA*mB/d^2

    so what if you put for mA 4, and mb .5, and d 3?

    How would that compare with the original force.

    I just don't understand the problem and i don't know how to solve it!
