Question

The unit of force in SI system is newton and it is given as 1 newton = `1kg m s^(-2)`. In CGS system its unit is dyne and it is given as 1 dyne = 1 g cm s^(2). Arrange the following steps in a sequential order to relate the SI unit and CGS unit of force.
(a) Write the conversations of kg and m, into g and cm, respectively.
(b) Substitute the conversations in 1 newton = `1 kg m s^(2)`Write the relation between 1 newton and dyne.
(d) Write in place of 1 g cm s^(-2) as 1 dyne
A. a c b d
B. a b d c
C. b d a c
D. c d a b

Answer 1

Correct Answer - B
The SI unit of force is newton, 1 newton = 1 kg m `s^(2)` . First convert kg and m into g and cm. Substitute these conversations in 1 newton = 1 kg m ` s^(-2)` . Now in the place of 1 g cm ` `s^(-2)`, write 1 dyne as 1 newton = `10 ^(5)` dyne.
