Question

if the mass of an object be 10 kg , what is its weight ?​

Answer 1

Answer:

98N or 100N(depending upon the value of 'g')

Explanation:

m=10kg

case 1,

g=10

w=mg

=10×10

= 100N

case 2,

g=9.8

w=mg

=10×9.8

=98N

Answer 2

Given:

Mass of object = 10 kg

To Find: Weight of body

Calculation:

• Weight of body is given as mass times gravitational acceleration.
• Weight is the force with which ground or earth pulls any objects towards its centre.
• Weight is the force exerted on a body in the downward direction.
• Weight is expressed in Newtons.
• Assume the gravitational acceleration of earth to be 9.8 m/$s^{2}$.

Formula for weight is:

Weight = mass * gravitational acceleration

Weight of body on earth = 10 * 9.8 = 98 Newton

Answer:

Weight of the object is 98 Newton.
