Question

Calculate the weight of the given object on the earth a part 50 gram of salt b. girl weight 52 kilogram C.8 milligram of gold

Answer 1

Given:

Mass of salt = 50 gram = 0.05 kg

Mass of girl = 52 kg

$\mathbf{\textrm{Mass of gold = 8 mg}=8\times 10^{-6}\ kg}$

To Find:

Find the weight of salt, girl and gold.

Solution:

We know that weight of object is given by:

Weight = Mass ×Gravitational acceleration

Gravitational acceleration is represented by g and its value is given:

$\mathbf{\textrm{Gravitational acceleration = g}=10 \ \frac{m}{s^{2}}}$

Weight of salt = 0.05 × 10 = 0.5 N

Weight of girl = 52 × 10 = 520 N

$\mathbf{\textrm{Weight of gold }=8\times 10^{-6}\times 10 =8\times 10^{-5} \ N}$

Answer 2

Explanation:

50gram =0.05kg

weight of salt =0.05×10=0.5N

weight of the girl 52×10=520N

6

weight of the gold 8×10
