If the distance between two objects, each of mass 'M', is tripled, the force of attraction between the two objects is:
a) 1/2 the original force
b) 1/3 the original force
c) 1/9 the original force
d) Unchanged
Ans:
If the distance in between 2 objects, each of mass 'M', is tripled, therefore force of attraction among the two objects is 1/9 the original force.
What is the work done to take a particle of mass m from surface of the earth to a height equal to 2R (R=radius of earth )? Ans) Initial PE= - GMm/R Final PE = - GMm/3R
