The dimensions of 1 ₀ ₀ are
Options
- AT^2/L^2
- BL/T
- CT/L
- DL^2/T^2
Correct answer
D. L^2/T^2
Step-by-step solution
The speed of light in vacuum is given by the relation: c = 1 ₀ ₀ Squaring both sides, we get: c^2 = 1 ₀ ₀ The dimensional formula for the speed of light c is [L T⁻¹] . Therefore, the dimensions of 1 ₀ ₀ are the same as the dimensions of c^2 . [ 1 ₀ ₀ ] = [L T⁻¹]^2 = [L^2 T⁻²] = L^2 T^2
