Question

If velocity, v = (A/B) [1-e to the power -t/B] where t is time, A & B are constants write the dimensions of A & B
​

Answer 1

Consider the given equation,

mu=A+λB+λ2C............(1)

Writing dimensional formula of m, u and lambda

Dimension of mu=[MLT−1]

Dimension of wavelength=[L]

Since, dimension of same quantity adds.

Put dimensions in (1)

[MLT−1]=A

[MLT−1][L]=B

[ML2T−1]=B

[MLT−1][L2]=C

[ML3T−1]=C

Dimension of A,B and C are calculated.
