0In the figure shown there are two blocks \( A \) and \( B \) of same mass connected with pulley and string to each other. Initially both of them are at a height of \( h=0.5 \mathrm{~m} \) from ground. After they are released they move in either direction and one of them strike the ground. For, the interval from releasing to when one of them strike, some physical quantities are in column I and their modulus values in SI units are in column II.
