Letter
A is incorrect because a positive charged object will attract a negatively

Let the beam is of length L
Now the stress on both the end is same
now we can say that torque on the beam due to two forces must be zero

also we know that stress at both ends are same


Now from two equations we have

solving above equation we have

<em>so the load is placed at distance 0.4L from the end of 12 mm^2 area</em>
