(b)
The two forces along the 
- direction balance each other.Hence, the resultant force is 
along the 
-direction. Let the point of application of the force be at (
)
(By symmetry, 
-coordinate will be zero)
For rotational equilibrium:
Alternative method:
Torque will only be produced by the two forces acting along 
-direction in anticlockwise direction. To balance this torque, we should apply a force 
in order to produce a torque in the clockwise direction, which is only possible if we apply a force at a point below the 
-axis
Then 
Next Question :
In the following question, numbers are arranged in a series with some principles understanding it. One term in the series is missing as shown by _________. This term is given as one of the alternatives amongst the four options given below it. Find this term.
