Ten one-rupee coins are put on top of each other on a table, Each coin has a mass m. Which of the following statements in not ture?

A

The force on the `6^(th)` coins (counted from the bottom) due to all the coins on its top is equal to 4 mg (downwards)

B

The force on `6^(th)` coin due to `7^(th)` coin is 4 mg (downwards)

C

The reaction of the `6^(th)` coin on the `7^(th)` coin is 4mg (upwards)

D

The total force on the `10^(th)` coins is 9 mg (downwards).

Text Solution

Verified by Experts

The correct Answer is:
D
10th coin, which is the topmost coin, experiences a reaction force of mg (upwards) from all the coins below it. So resultant force is 9mg.
