Question

If the acceleration due to gravity be taken as the unit of acceleration and the velocity generated in a falling body in one
second as the unit of velocity then
(a) The new unit of length is g metre(b)
The new unit of length is 1 metre
(c) The new unit of length is gametre
(d) The new unit of time is - second​

Answer 1

the new unit of length is 1 metre because unit of acc. due to gravity is g(m/s^2) and the unit of velocity in one second is m/s then unit of length has to be 1 metre.

Hope it helps...

Answer 2

Answer:

a is the correct answer

v=LT^-1 _eq1

a=LT^-2 _eq2

now squaring both sides of equation1 nd dividing by eq2 we get

v^2=L

L=L×LT^-2

newlength is g metre
