A spherical ball is compressed by 0.01% when a pressure of 100 atmosphere is applied on it. Its bulk modulusof elasticity in dyne/cm2 will be approximately[1] 1012[21 1014[3] 10[4] 1024

Answer»

Let origonal volume be V and original pressure= 1 atm

New volume =0.01%V = 0.0001V

New pressure=100 atm

Bulk moulus, K =-V. ∆P/∆V [ pressure is increased while volume is decreased]

K= -V. (100–1)/(V-0.0001V)

K= —99/0.9999

K= —99.009901 atm
