1.	A solid sphere of radius 10 cm is subjected to a pressure of 5 xx 10^(8) Nm ^(-2),then determine the change in its volume. Bulk modulus of material of sphere is 3.14 xx 10 ^(11) Nm ^(-=2).
Answer» <P> Solution :`B = (P)/( Delta V //V) ` ( Neglecting negative sign) `therefore Delta V = (PV)/(B)` `= (5 xx 10 ^(8) xx (4)/(3) pi r ^(3))/( 3.14 xx 10 ^(11))` `= ( 5 xx 10 ^(8) xx 4 xx 3.14 xx (0.1) ^(3))/( 3.14 xx 10 ^(11) xx 3)` `= 0.00666 xx 10 ^(-3)` `~~ 6.7 xx 10 ^(-6) m ^(3)`
