Which of the following is the correct relation?
a) 1 Kg = 100 g
b) 1 Kg = 1 g
c) 1 g = 0.001 Kg
d) 1 g = 0.01 Kg

Answer

A, B, D

Explanation

a. When the ruler makes uniform circular motion in the horizontal plane .
`mu mg=mw_1^2L`
`w_1=sqrt(mug)/L`

b. When the ruler makes uniformly accelerated circular motion ure.
`mu mg=sqrt((momega^2_2L)^2+(mLalpha^2))^2)`
`rarr omega 4/2 +alpha^2= (mu^2g^2)/L^2`
