`OABC` is a current carrying square loop an electron is projected from the center of loop along its diagonal `AC` as shown. Unit vector in the direction of initial acceleration will be
.

A

`hatk`

B

`-((hati+hatj)/(sqrt2))`

C

`-hatk`

D

`(hati+hatj)/(sqrt2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`oversetrarrF = -e (oversetrarrV xx oversetrarrB)`
Force will be along `BO` or unit vector
`= -(hati + hatj)/(sqrt2a` .
