Question

please answer it. very urgent so please answer it fastly​

Answer 1

Answer:

3)

Explanation:

the power of e is constant so

v/b is 1

b=v

and dimension of v is LT^-1

so it is equal to b also

now F=a²/b

dimension of F is MLT^-2

MLT^-2=a²/LT^-1

so

a²=[MLT^-2][LT^-1]

=ML²T^-3

a⁴=M²L⁴T^-6

b^-2=L^-2T²

so a⁴b^-2=(M²L⁴T^-6)(L^-2T²)

=M²L²T^-4
