Q7
An object having 10 kg mass weighs 9.81kg on a spring balance. The value of ‘g’ at this place is
A.
10 m/sec2
B.
9.81 m/sec2
AnswerC.
10.2 m/sec2
D.
9.75 m/sec2
Answer: Option B
Solution
Answer: Option B
Solution:
Weight (W) is the force exerted by gravity on an object and is given by the formula W = m * g
Here, the mass (m) of the object is 10 kg
The weight of the object as measured by the spring balance is 9.81 kg (which is actually a measure of force in newtons but given in kg for simplicity)
To find the acceleration due to gravity (g) at this place, we use the formula:
g = W / m
Substituting the given values:
g = 9.81 kg / 10 kg
g = 9.81 m/sec2
Therefore, the value of 'g' at this place is 9.81 m/sec2
