Can matching the dimensions of length, g and mass give the complete formula for a pendulum's period? Assess the Assertion (A) and Reason (R).

  • Assertion (A): The formula T = 2π√(l/g) for a simple pendulum cannot be derived completely by dimensional analysis.
  • Reason (R): Dimensional analysis gives no information about dimensionless constants.
