Which of the following are correct according to Boyle's law ?

Answer»

`((del P)/(del V))_(T)=(K)/(V^(2))`
`((DV)/(dP))_(T)`
`((dV)/(dP))_(T)=-(K)/(P^(2))`
`((dV)/(dP))_(T)=+(K)/(P)`

Solution :`V prop""(1)/(P) RARR V=(K)/(P)`
`therefore ((dV)/(dP))_(T)=-(K)/(P^(2))`
Also, `P=(K)/(V)`
`((dP)/(dV))_(T)=-(K)/(V^(2))`
HENCE, (A) and (C ) are the correct answer.
