Question

If the numerical value of work is 40 units
in a system. If the units of fundamental
quantities are doubled, its value will be
1.200units
2.400 units
3.800 units 4.100 units​

Answer 1

TOPIC :- UNIT AND MEASUREMENT

CONCEPT :- Work = F × s. It implies that dimension in terms of fundamental quantity will be

[tex]{m {l}^{2} {t}^{ - 2} [tex]

Now,

Given,

{m {l}^{2} {t}^{ - 2} = 400

{2m {2l}^{2} {2t}^{ - 2} = 2 × 400 = 800 units
