Answer:
0.0481 N
Explanation:
The mass of a body is the quantity of matter stored in that body. It is a property that measures resistance to acceleration when a force is applied. The S.I unit of mass is the kilogram (kg).
The weight of a body is the force exerted on that body by gravity. The S.I unit of weight is the Newton (N). The weight of an object can also be defined as the force acting on the object. The formula for weight is:
Weight (W) = Mass (m) × acceleration due to gravity(g).
Giving that: mass (m) = 4.9 g = 0.0049 g and acceleration due to gravity (g) = 9.81 m/s².
Therefore, Weight (W) = 0.0049 × 9.81 = 0.0481 N
