Three forces of magnitudes 6 N, 6 N an d `sqrt(72)` N act at corner of cube along three sides as shown in figure. Resultant of these forces is

A

12 N along OB

B

18 N along OA

C

18 N along OC

D

12 N along OE

Text Solution

Verified by Experts

The correct Answer is:
d
Resultant to 6N and 6N is `sqrt(72)` N along OB now there are two forces of `sqrt(72)`N which are perpendicular to each other their resultant is `sqrt(72+72)=sqrt(144)=12 N` the resultant is directed towards the angle bisector i.e along OE
