Explanation:
Given
mass of bus along with travelers travelling in North direction is
speed of bus towards North
mass of bus travelling in South direction is
speed of bus
mass of each Passenger in south moving bus
Momentum of North moving bus
Momentum with south moving bus
For total momentum to be towards south
should be greater than 0
thus for least value of n

The correct answer is A) decreases, because the gravitational force is inversely proportional to the square of the distance. In fact, the magnitude of the gravitational force between two object of mass M and m, at a distance d one from each other, is
where G is the gravitational constant. As can be seen from the formula, if the distance d between the two object increases, the intensity of the force decreases.
