A small body of mass 0.5kg is allowed to slide on an inclined frictionless track from rest position as shown in fig. If h is double the minimum height required to complete loop sucessfully, calculate the force on the block at position H in newton.

Total force will be normal force at that point + centrifugal force
Therefore, F= mv^2/r + mg
Since to complete a circle v=√5gr
Therefore F= 5mg + mg = 6mg = 30N
