Ten 1 rupee coins are put on the top of each other on the table.Each coin has a mass of m The ratio of reaction of 5^( th ) coin to the force on 4^(th ) coin ?

Ten one-rupee coins are put on top of each other on a table. Each coin has a mass m . Give the magnitude and direction of (a) the force on the 7^(th) coin (counted from the bottom due to all the coins on its top. (b) the force on the 7^(th) coin by the eight coin. (c) the reaction of the 6^(th) coin one the 7^(th) coin.

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

One dozen coins were arranged one above the other. Their total height was 6cm 6mm. The thickness of each coin is

If three one rupee coins can be placed around a ten-paise coin such that each one rupee coin touches the ten paise coin as well as the other two one-rupee coins,the ratio of the radii of the one rupee and ten paise coin is:
