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 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?

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?

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:

if three 1rupee coin can be placed around a 10 paise coins such that each one rupee coin touches the 10 paise coin as well as the other 1 rupees coins,the ratio of the radii of 1 rupee and 10 paise coin is:

A bag contains one rupee, 50 paise and 25 paise coins. The ratio of the number of 1 rupee coins to that of 50 paise coins is 5 : 9 and the ratio of the number of 50 paise conins to that of 25 paise coins is 2 : 1 . Find the value of the 50 paise coins in the bag if the total value of the bag is Rs. 425.
