Question

dimensional formula of pressure is M^aL^bT^c. Then find a-b-c​

Answer 1

Given

Dimesional formula of pressure = Mᵃ Lᵇ Tᶜ

➺ (1)

To find

Value of a, b and c

Solution

We know that:

Pressure = Force/ Area

➺ Pressure = M L T⁻² /L²

➺ Pressure = [M L⁻¹ T⁻²] ➺ (2)

Comparing (1) and (2), we get:

a = 1, b = -1, c = -2
