A particle is moving eastwards with a velocity of 5 m/s. In 10s the velocity changes to 5 m/s northwards. The average acceleration in this time is

A

zero

B

`(1)/(sqrt2)m/s^(2)` towards north-west

C

`(1)/(sqrt2)m/s^(2)` towards north-east

D

`(1)/(2)m/s^(2)` towards north-west

Text Solution

Verified by Experts

`veca= (dvecv)/(dt)=(5)/(10)(hatj-hati)`
`a=(1)/(sqrt2)ms^(-2)`
