Question

2)Check the correctness of the equation using dimensional

analysis

V= g h

Where v: velocity

g: acceleration due to gravity

h: height​

Answer 1

Answer:

The equation is incorrect.

Explanation:

Dimensions of velocity = [LT^-1]

Dimensions of acceleration due to gravity = [LT^-2]

Dimensions of height = [L]

Given : v=gh

[LT^-1] = [LT^-2][L]

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

which is incorrect ,they are not equal.

so the equation is dimensionally incorrect.
