Question

How to calculate the direction of Normal Force applied when we push any body against the wall??

Answer 1

it will be perpendicular to the centre of mass of the object
in the direction opposite to the line of impact

Answer 2

The normal force will act perpendicular to the common tangent of the body and the wall at the point of contact

Answer 3

perpendicular to the centre of mass, ,

Answer 4

excuse me..the centre of mass is a point...there is no perpendicular defined to a point

Answer 5

@ mr.knowledgeable & tianpradana: you both are wrong.

him1618 says correct. In other word, we can say normal force is always perpendicular to the surface.

to calculate the normal force we decompose other forces acting on the body and the magnitude of the force opposite and in the direction of normal force is equal to the magnitude of normal force.

Thankya guys !!!!!
