Question

The dimensional formula for product of resistance and conductance is same as for dielectric constant. Both have dimensions of time constant.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (C)

If assertion is true but reason is false

Answer 2

Both the quantities are dimensionless. Resistance $\times$ conductance $=R \times 1 / R=\left(M^{0} L^{0} T^{0}\right)$ $=1$ and Dielectric constant $K$ is dimensionless.
