We know torque
For this problem
=90o.
Here r is the perpendicular distance and F is the magnitude of the applied force.
Let the perpendicular distance for F1=r1 .
Let the perpendicular distance for F2=r2.
Let the perpendicular distance for F3=r3.
Let the perpendicular distance for F4=r4.
From the figure we can say
From the equation (i) we can say option
is correct.
