Questions
The normal density of a material is and its bulk modulus of elasticity is K. The magnitude of increase in density of material, when a pressure P is applied uniformly on all sides, will be:
detailed solution
Correct option is C
Mass = density × volume ⇒m=ρV⇒0=ρdV+Vdρ⇒dρ=−ρdVV Also, Bulk Modulus =K=−dPdVV⇒dVV=−dPK Thus, dρ=ρdPK here dP=P( given )⇒ Increase in density =dρ=ρPKTalk to our academic expert!
