Question

anyone there to answer this

Answer 1

(a) is correct option because
torque= F× perpendicular did.
then( 7×2)N
will take object upward and( 11×4)N will take object downward
in this way object will rotate about O so total torque
44+14=58N

Answer 2

Hii friends,

The correct answer is option (B).

Reason:-

We know the formula,

Tau = F×r sin (theta)

(Here all are in perpendicular direction)

;- sin 90°=1

Tau (up)= 7×2

Tau(up) =14 N m

Tau(Down) = 11 ×4

Tau (Down) = 44N m

At centre,

Tau = 44-14

Tau => 30N m.

:-option (B) is the correct answer.

Hope this helps you a little!!!!
