PHY 101 Physical Quantities And Units Objective Question

Question

The dimensional formula for a is the same as that for:
Options
A V²
B P
C PV²
Correct Answer
D RT
Correct Answer

Option C is the correct answer.

Detailed Explanation

In the term a/V², a/V² must have same dimension as P (pressure). So [a] = [P][V²] = ML⁻¹T⁻² * L⁶ = ML⁵T⁻². PV² has dimensions (ML⁻¹T⁻²)(L⁶) = ML⁵T⁻².

Hint

Each term in the equation must have the same dimension (pressure).
