newton's laws of universal gravitation given: M1=41kg M2= 12KG r=1.5m 1. Solve for Fg. 2. R is constant, M1is doubled, M2is constant, Find Fg , will the attraction become stronger or weaker? 3. M1 is constant , M2 is constant, R is doubled, Solve for Fg . Will it become weaker or stronger? 4. M1 is constant, M2 is constant, R is reduced to half. What is Fg? Will it become stronger or weaker
