Explanation:
Force = mass × acceleration due to gravity(g) [g = 10 m/s²]
=> 2 = mass × 10
=> mass = 2/10 Kg = 1/5 Kg
Converting Kg into g,
1/5 × 1000 = 200 g
Let numbers of chips be y.
Now,
Mass of the container + mass of the chips = Total mass
50 g + 2 g (y) = 200 g
2 g (y) = 150 g
y = 150 g/2 g
y = 75
So, number of chips = 75.
Hope it helps.
