If block A is moving with an acceleration of `5ms^(-2)`, the acceleration of B w.r.t. ground is

A

`5 m//s^(2)`

B

`5sqrt(2) m//s^(2)`

C

`5sqrt(5) m//s^(2)`

D

`10 m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
For B :
Net acceleration
`=sqrt(5^(2)+10^(2))=sqrt(125)=5sqrt(5) ms^(-2)`
