Q96 / 180 · AIIMS 2009 · Physics

Assertion : The dimensional formula for product of resistance and conductance is same as for dielectric constant. Reason: 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
  • Correct answer
    C
    If assertion is true but reason is false
  • D
    If both assertion and reason are false.

Solution

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

Hence, the correct answer is option: 'C'.
