Question

dimensional formula of mc^2​

Answer 1

Explanation:

The dimensional formula of energy is given by,

M1 L2 T-2

Where,

M = Mass

L = Length

T = Time

Answer 2

Answer:

Dimensional formula of mc² :

m = mass = [M]

c = speed of light = [M⁰ L T⁻¹]

c² = [M⁰ L T⁻¹]² = [M⁰ L² T⁻²]

Here M = mass, T = time and L = length.

Energy = m × c²

⇒ E = [M] × [L¹ T⁻¹]² = M¹ L² T⁻²

= M¹ L² T⁻².
