Newton's Laws O...

Ten coins are placed on top of each other on a horizontal table. If the mass of each coin is 10 g and acceleration due to gravity is 10 ms^–2, what is the magnitude and direction of the force on the 7^th coin (counted from the bottom) due to all the coins above it?

Directions: In the following question, Statement-1 (Assertion) is followed by Statement-2 (Reason). There are four choices given below the statements, out of which only one choice is correct.

Statement-1: When a ball dropped from a certain height hits the floor, it exerts a force equal in magnitude to its rate of change of momentum.

Statement-2: The floor does not move because the action and reaction forces, being equal and opposite, cancel each other.
