Question

The dimensional formula for the product

of two physical quantities P and Q is

2 2 L T 

    the dimensional formula of P/Q is

2

  T  the P and Q respectively are​

Answer 1

A/Q,

P•Q = 22 => P= 22/Q

P/Q=2 => 22/Q = 2Q => Q²= 2×2×11

=> Q=2×√11

Now,

P= 22/Q => P= 11/√11 = √11

(as, (√11×√11)=11 )
