Question: Planet P has a diameter twice as large as the Earth s , and a mass that is eight times that of the Earth s

Planet P has a diameter twice as large as the Earths, and a mass that is eight times that of the Earths. What is gP, the value of the gravitational acceleration on the surface of this planet, as compared to gE, the gravitational acceleration on the surface of the Earth? A gP =8 gE B gP = gE C gP =0.5 gE D gP =4 gE E gP =2 gE
