Question

If an object's weight is 100N and the gravitational field strength is 2.5N/kg, what is it's mass?

Answer 1

Answer:

61.35

Explanation:

Solution

m=Wg=100N1.63m/s2=61.35Kgm=Wg=100N1.63m/s2=61.35Kg

The mass of the body = 61. 35 kg.

Answer 2

Answer:

The mass of the object with 100 N weight and 2.5 N/kg gravitational field strength is found out as 40 kg.

Explanation:

The weight of an object and its mass are directly proportional. For a given gravitational field strength, the greater the mass of the object, the greater its weight. Weight can be calculated using the equation: weight = mass × gravitational field strength. W = m g This is a way of measuring how much gravity there is. The formula is: weight/mass = gravitational field strength. On Earth the gravitational field strength is 10 N/kg. Other planets have different gravitational field strengths.

It is given to us that -

The object's weight = 100 N

The gravitational field strength = 2.5 N/kg

We have to find out the mass of the object.

We know that the formula for weight of an object is given as -

W = m * g ----- (1)

where,

m = mass of the object

g = gravitational field strength

Substituting the given values of weight of the object and gravitational field strength in the equation (1),

we can find out the mass of the object as -

W=mg

m=W/g

m=100/2.5

m=40 kg

Thus, the mass of the object with 100 N weightand 2.5 N/kg gravitational field strength is found out as 40 kg.
