Question

A mobile phone has a mass of 100g . find its weight if g is 10 N kg-1​

Answer 1

$\huge{\star}{\underline{\boxed{\red{\sf{Answer :}}}}}{\star}$

Weight of Mobile phone is 100 g.

If acceleration due to gravity is 10 m/s² .

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

We know that

$\LARGE{\boxed{\boxed{\sf{Weight \: = \: Mass \: \times \: g}}}}$

Weight = 100 × 10

Weight = 1000 g

Or

Weight of phone is 1 kg

$\LARGE{\boxed{\sf{Weight \: = \: 1 \: kg}}}$

Answer 2

${\bold {\huge {\red {\underline {\green {\mathcal {ANSWER:}}}}}}}$

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
