Question

The mass of an object is 4.2kg. Find its weight ​

Answer 1

Answer:

The mass of the object =4.2kg

weight =?

weight =mg

weight = 4.2kg ×9.8

weight =41.16N.

Hope it helps u mate

Answer 2

Provided that:

• Mass = 4.2 kg
• Weight = ???

Solution:

• Weight = 41.16 or 42 Newton

Using concept:

• Formula to calculate weight

Using formula:

• W = mg

Where, W denotes weight, m denotes mass and g denotes acceleration due to the gravity.

Knowledge required:

• g denotes acceleration due to gravity and the value of g is 9.8 metre per second sq.

• SI unit of weight = Newton

Required solution:

→ W = mg

→ W = 4.2 × 9.8

→ W = 41.16 N

→ Weight = 41.16 Newton

__________________________

~ We can take 10 m/s sq. as the value of g here too for easy calculation

→ W = mg

→ W = 4.2 × 10

→ W = 42 N

→ Weight = 42 Newton $\:$
