In the cube of side 'a' shown in the figure, the vector from the central point of the face ABOD to the central point of the face BEFO will be :

A

`(1)/(2) a(hat(j)- hat(k))`

B

`(1)/(2) a(hat(j)- hat(i))`

C

`(1)/(2) a(hat(k)- hat(i))`

D

`(1)/(2) a(hat(i)- hat(k))`

Text Solution

Verified by Experts

The correct Answer is:
B

`vec(r)= vec(r)_(B) - vec(R)_(A)= - (a)/(2) hat(i) + (a)/(2) j`
