Yes normal reaction can do workSuppose a block is kept on an inclined plane Now if the plane is pushed the block is also displaced Now the forces acting on the body are its weight and the normal due to the inclined surface Here displaced is not perpendicular to the normal and thus work done is non zero

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
