If H is the harmonic mean between Pa n d...

If `H` is the harmonic mean between `Pa n dQ` then find the value of `H//P+H//Qdot`

A

2

B

`(PQ)/(P+Q)`

C

`1/2`

D

`(P+Q)/(PQ)`

Text Solution

Verified by Experts

The correct Answer is:
a
Since , ` H = (2PQ)/(P+Q) rArr H/P = (2Q)/(P+Q) and H/Q = (2P)/(P+Q)`
` :. H/P +H/Q = (2Q)/(P+Q) +(2P)/(P+Q) =2`
