Question

Find the dimension of a/b in the equation p=a-t2/bx where p is power,x is distance and t is time.​

Answer 1

Answer:

Dimensions of Power: P−ML

2

T

−3

Since the given expression is dimensionally correct, each term of the expression must have same dimensions as that of power.

Therefore,

[a][t]

[x

2

]

=

[a]T

L

[a][t]

[b]

=

(M
