Assertion : All derived quantities may be represented dimensionally in terms of the base quantities.
Reason : The dimensions of a base quantity in other base quantities are always zero.

Text Solution

Verified by Experts

The correct Answer is:
(A) s, (B) p, (C) r, (D) q
Electric field `vec(E)=-(del V)/(delx)hat(i)-(delV)/(dely)hat(j)`
For (A): `vec(E)=-hat(i)+1/sqrt(3)hat(j)`
For (B): `vec(E)=+hat(i)`
For (C): `vec(E)=-hat(i)+sqrt(3)hat(j)`
For (D): `vec(E)=+1/sqrt(3)hat(i)+sqrt(3)hat(j)`
