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 angle 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 of these forces is
`R = sqrt((6)^(2) + (6)^(2) + sqrt((72)^(2))) ` along OE
` = sqrt(36 + 36 + 72) = 12` N along OE
