Question

A force F is given by F = at + bt², where t is time. What are the dimensions of a and b? *

Answer 1

Explanation:

MLT-2 = a*T + b*T2

a*T = MLT-2

a= MLT-3

SIMILARLY,

b = MLT-4

Answer 2

Answer:

a=u,b=a

here in at stands for initial velocity (u) and time

whereas bt^2stands for acceleration (a)t^2
