What is the force of gravity exerted on an object having a mass of 5 tonnes?

• A. 4.905 N
• B. 49.05 N
• C. 490.50 N
• D. 49,050 N

Answer: (D)

To determine the force of gravity exerted on an object, you can use the formula: \[ F = m \times g \] where: - \( F \) is the force of gravity (in newtons), - \( m \) is the mass of the object (in kilograms), - \( g \) is the acceleration due to gravity, which is approximately \( 9.81 \, \text{m/s}^2 \) on the surface of the Earth. In this case, the mass is given as 5 tonnes. Since 1 tonne is equal to 1,000 kilograms, 5 tonnes is equal to: \[ 5 \, \text{tonnes} = 5,000 \, \text{kg} \] Now, substituting the values into the formula: \[ F = 5000 \, \text{kg} \times 9.81 \, \text{m/s}^2 \] \[ F = 49,050 \, \text{N} \] Thus, the force of gravity exerted on an object with a mass of 5 tonnes is 49,050 N. This option is the correct calculation based on the principles of physics

To determine the force of gravity exerted on an object, you can use the formula:

[ F = m \times g ]

where:

• ( F ) is the force of gravity (in newtons),

• ( m ) is the mass of the object (in kilograms),

• ( g ) is the acceleration due to gravity, which is approximately ( 9.81 , \text{m/s}^2 ) on the surface of the Earth.

In this case, the mass is given as 5 tonnes. Since 1 tonne is equal to 1,000 kilograms, 5 tonnes is equal to:

[ 5 , \text{tonnes} = 5,000 , \text{kg} ]

Now, substituting the values into the formula:

[ F = 5000 , \text{kg} \times 9.81 , \text{m/s}^2 ]

[ F = 49,050 , \text{N} ]

Thus, the force of gravity exerted on an object with a mass of 5 tonnes is 49,050 N. This option is the correct calculation based on the principles of physics
