Which of the following functions is a solution for the differential equation ` xy’-y=0`?
`a) y=4x`
`b) y=x^2`
`c) y=-4x`
`d) y=2x`

Text Solution

Verified by Experts

The correct Answer is:
C, D
According the question
`8g=F_1+F_2`
=N_1=N_2`
Since `R_1=R_2`
Therefore `F_1=F_2`
`rarr 2F_1=8g`
`rarr F_1=40`
Let us take torque about the point B we will get
`N_1xx4=8gx0.75` ltbr `rarr N_1=((50x3))/((4xx4))=15N`
Therefore `sqrt(F_1^2+N_1^2)=R_1`
`=sqrt(40^2+15^2)`
`=42.72=43N`
