Question

The dimensional formula of the force is-
1. M¹L¹T^-2
2. M1L1T-1
3. M2L1T1
4. M1L0T2

Answer 1

Correct Answer - Option 1 : M¹L¹T^-2

The correct answer is option 1) i.e. M1L1T-2

CONCEPT:

• Force is defined as the push or pull acting on an object.
  • It's SI unit is the newton (N)

The force acting on an object of mass (m) with an acceleration (a) is given as:

Force = m × a

EXPLANATION:

Dimensional unit of mass = M¹

Dimensional unit of acceleration (unit: m/s²) = L¹T^-2

We know, Force = m × a

Therefore, the dimensional formula of force = M1L1T-2
