Question

A mobile phone has a mass of 100g. Find its weight if g is 10Nkg-1

Answer 1

Weight of Mobile phone is 100 g.

If acceleration due to gravity is 10 m/s² .

===================

We know that

Weight = 100 × 10

Weight = 1000 g

Or

Weight of phone is 1 kg

Answer 2

Answer:

Plz mark my answer as a brainliest answer      ^_^

Step-by-step explanation:

The force on earth due to gravity is:

F=mg

where ,

m= mass of the object (0.1 kg given)

g= 10N kg-1 (given)

so according to question

F = 0.1 × 10

F= 1 N/kg

Another way is

Weight of Mobile phone is 100 g.

If acceleration due to gravity is 10 m/s² .

===================

We know that

Weight = 100 × 10

Weight = 1000 g

Or

Weight of phone is 1 kg
