Test Academy | A sphere of small size is at the bottom of a lake of depth 200 m. Due to pressure its fractional change in volume is α x 10 -7 . What is value of α , if bulk modulus of sphere is 5 x 10 12 Pa? (Use g = 10 m/s 2 )

Question

A sphere of small size is at the bottom of a lake of depth 200 m. Due to pressure its fractional change in volume is α x 10^-7. What is value of α , if bulk modulus of sphere is 5 x 10¹² Pa? (Use g = 10 m/s²)
