Question

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

Answer 1

$a - {m}^{1} {l}^{1} {t}^{ - 3} \\ \\ b - {m}^{1} {l}^{1} {t}^{ - 4}$

Answer 2

F=at+bt²
dimension of at= dimension of F
dimension of a=[MLT^-2]/[T]
dimension of a =[MLT^-3]
dimension of bt²= dimension of F
dimension of b=[MLT^-2]/[T²]
dimension of b=[MLT^-4]


hope dis help
