The sum of these three vectors is :

A

`4hat i+4 hatj`

B

`5hat I -2 hat j`

C

`4hat i+3hat j`

D

`5hat i+8hat j`

Text Solution

Verified by Experts

The correct Answer is:
d
`(10 cos 37 hati +10 sin 37 hatj)+6sqrt(cos 45(hati)+6sqrt(2)sin 45 hatj)+(5 cos 53 hat i+ 53(hatj)=(8hati+6hatj)+(-6hati+6hatj)+(3hati-4hatj)=5hati+8hatj)`
