Question

If the unit of force and length each be
increased by four times, then the unit of
energy is increased by [CPMT 1987]
(a) 16 times
(b) 8 times
(c) 2 times
(d) 4 times​

Answer 1

Answer:

option B 8s correct hope its helpful for you

Answer 2

Answer:

16 time

Step-by-step explanation:

unit of energy = kg. m2/s2

unit of force = kg. m/s2

unit of length = m

thus the unit of energy in terms of unit of force

and length is given by

unit of energy = ( kg.m/ s2) × (m)

if the unit of length and force are increased by four times

the unit of energy will be :

unit of energy = (4.kg.m/ s2) × (4m)

unit of energy= 16 (kg.m2/s2)

therefore if the unit of length and force are increased by four times,the unit of energy will change by 16 time.
