A square paper thread is made from the remaining paper, after paper toys are made . After it is dipped in water due to presence of surface tension the sides of the square get stretched . If Young 's Modulus is Y , and surface tension of water is T . calculate Angle of deviation of the paper side . Note :- assume radius of paper to be "r" and length of total thread to be equal to "l"
