When a force of 6.0 N is exerted at 
to a wrench at a distance of 8 cm from the nut, it is just able to loosen the nut. What force F would be sufficient to loosen it, if it acts perpendicularly to the wrench at 16 cm from the nut
Text Solution
Verified by ExpertsThe correct answer is:
D
A force of 6 N acting at an angle of 
is just able to loosen the wrench at a distance 8 cm from it.
Therefore total torque acting at A about the point 0
Therefore total torque required at B about the point 0
