Question

The velocity of a particle v at an instant t is given by v= at+bt^2 . The dimensions of b is ? Please answer​

Answer 1

Answer:

The velocity of a particle v at an instant t is given by v = at + bt2 the dimension of b is. [L] [LT-1] [LT-2]

Answer 2

Answer:

v= at + bt^2

By principle of homogeneity , we get

v = at + bt^2

v= bt^2

[L T^-1] = b [T^2]

b= [L T-1]/ [T^2]

b= [ L T^-3]
