Given :
Three boxes of masses 2kg, 3kg and 5kg.
Total mass resting on table= 5+3+2=10kg
Normal force = W as they are balanced forces.
N=w=mg=10x9.8=98N
the normal force exerted by the 5 kg box on the 3 kg box is 98N

Hey there!
Total mass = (2+3+5)kg = 10 kg
Then,
Normal force = weight [balanced forces]
Normal force = mg
= 10 × 9.8
= 98 newton
Total mass = (2+3+5)kg = 10 kg
Then,
Normal force = weight [balanced forces]
Normal force = mg
= 10 × 9.8
= 98 newton
