Question

If the units of length, velocity and force are half,
then the units of Power will be :-
(1) doubled
(2) halved
(3) one fourth
(4) remains unaffected

Please give the correct method of this question ​

Answer 1

If the units of length, velocity, and force are half, then the units of Power will be one-fourth.

Step-by-step Explanation:

• As we know that power is energy or work done per unit of time. So its formula is
• P = Work done / time =  W/t
• Work done = forced displament i.e W = F.d
• P = Fd/t = Fv
• P = (F /2)(v/2)
• P = Fv/4
