Peak value divided by the rms value gives us

A

Peak factor

B

Crest factor

C

Both peak and crest factor

D

Neither peak nor crest factor

Text Solution

Verified by Experts

The correct Answer is:
A
Mass of lower block `m_(1)=200rho` and
`vec(r_(1))=(10,5)cm`
Mass of middle block `m_(2)=100rho` and
`vec(r_(2))=(5,15)cm`
Mass of upper block `m_(3)=200rho` and
`vec(r_(3))=(10,25)cm`
`therefore vec(r_(cm))=(m_(1)vec(r_(1))+m_(2)vec(r_(2))+m_(3)vec(r_(3)))/(m_(1)+m_(2)+m_(3))`
`=(200rho(10,5)+100rho(5,15)+200rho(10,25))/(200rho+100rho+200rho)`
`=((2000,1000)+(500,1500)+(2000,5000))/(500)`
`=((4500,7500)/(500))`
`=(9,15)cm`
