Five points given by A,B,C,D and E are in a plane. Three forces AC,AD and AE act at A annd three forces CB,DB and EB act B. then, their resultant is

A

2AC

B

3AB

C

3DB

D

2BC

Text Solution

Verified by Experts

The correct Answer is:
B
Points `A,B,C,D and E` are in a plane.
Resultant`=(AC+AD+AE)+(CB+BD+EB)`
`=(AC+CB)+(AD+DB)+(AE+EB)`
`=AB+AB+AB=3AB`
