Question
There are two balls located in deep space as shown in the figure. The black ball has mass 60kg and the red ball has mass 12kg. The distance between the two balls is r=28cm.
(a) Find the magnitude of the acceleration of the red ball, a. m/s2
(b) If r is 4 times larger, with what factor will the acceleration a change?
(c) If the mass of the black ball is 25 times larger, with what factor will the acceleration a change?
(d) If the mass of the red ball is 40 times larger, with what factor will the acceleration a change?

(c) If the mass of the black ball is 25 times larger, with what factor will the acceleration a change? (d) If the mass of the red ball is 40 times larger, with what factor will the acceleration a change?Explanation / Answer
a) calculate the expression to get the value
a = G*60/0.28*0.28
b) ir r is increased 4 times acceleration goes 1/16 times
c) If the mass of the black ball is 25 times larger, acceleration increases 25 times
(d) If the mass of the red ball is 40 times larger, acceleration will be the same
