Per NCERT 'Ready to Go Beyond' box (§6.3), an object resting on a horizontal surface has gravitational force (weight) acting downward. What force from the surface BALANCES this?
AThe NORMAL force — perpendicular to the surface, acting upward on the object
BAn attractive force from the air
CNo force at all
DFriction
Answer & Solution
Correct answer: A. The NORMAL force — perpendicular to the surface, acting upward on the object
Per NCERT §6.3, the normal force from the surface balances gravity on a horizontal surface. The other options misstate.
