Question
if INSTEAD, when the mass is at the point B, we are told that the surface of the tube only above point C HAS friction, and that the average frictional force is 35.2N, find the new maximum height above point B to which the mass rises Two spherical masses of m1 = 400.0 kg and m2 = 250.0 kg are separated from their centers by 8.00 meters, as shown. find the gravitational field at print A which is 5.00 m from m1 and is on the line between the two masses A small mass of m3 = 2.00 kg is placed at B, on the line connecting the centers of the two larger masses. How far is point B from mass m1 if the force on m3 due to the larger mass m1 is four times as large as the force on m3 due to the smaller mass m2?Explanation / Answer
F = Gm1/d^2-Gm2/d2^2 = G*400/25 - G*250/9 = 7.856 x 10^-10 N (TOWARDS m2)
b) Gm1/x^2 = Gm2/(d-x)^2
=> 400/x^2 = 250/(8-x)^2
=> 20/x = 510/8-x
=> x = 32/(4+10)
Hope my short and clear explanation helped :)
