Question

If the mass of an object be 10 kg, what is its weight? (g = 9.8 m/s2).

Answer 1

Answer:

Weight is 98 N.

Explanation:

m = 10 kg

g = 9.8 m/s²

Weight = Force applied by earth

So,

F = m * a

=> F = m * g

=> F = 10 * 9.8

=> F = 98 N

So,

Weight is 98 N.

Answer 2

Given:

• The mass of the object = 10 Kg
• g = 9.8 $m/s^2$

To Find:

• The weight of the body.

Solution:

The formula to find the weight is given by,

F = m × g → {equation 1}

Where "g" is the gravitational force, "m" is the mass.

On substituting the given values in equation 1 we get,

⇒ F = 10 × 9.8 {multiplying the terms, the value of "g" is constant}

⇒ F = 98 N { force applied by earth = weight}

∴ W= 98 N

∴ The weight of the object = 98 N.
