Answer 2

Answer:

(3)

Explanation:

Given the fundamental units of length,velocity and force are doubled.

⇒Length Dimensions are =L

⇒V=Displacement /Time

Velocity Dimensions= LT⁻¹

In order to make velocity  double , already length is doubled.

So no change in Time.

⇒Force=ma

Force dimensions=MLT⁻²

already length is doubled to make force double .

So no change will be there in mass . It will be constant.

⇒But momentum will change 

As Momentum=mxV

Momentum units =MLT⁻¹

so here mass and time are constant. So L is doubled. Momentum will double

Energy will become four times

Energy dimensions=ML²T⁻²

As length doubles, energy becomes 4 times.

So correct option is 3 :MOMENTUM WILL DOUBLE
