Normal reaction is the force acting between two contact surfaces. Like, if you push a wall, you will feel an opposite force acting on your hands. That''s normal reaction.
You can find it by Newtons third law, action and reaction are equal. For example, if a block of 2 kg is lying on a table, it exerts a force of 20N (Mg) on the table, thus the normal reaction is also 20N
Approve if i helped :)

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
