The weight of a body will be maximum at- Correct Answer Poles
CONCEPT:
- Acceleration due to gravity (g): It is the free-fall acceleration of an object in a vacuum without any drag.
- This is the steady gain in speed caused exclusively by the force of gravitational attraction.
- The standard value of g on the surface of the earth at sea level is 9.8 m/s2.
- The value of g is comparatively more at the pole than that of the equator
The acceleration due to gravity is given by:
g = GM/r2
W = mg
where, w = weight ,m = mass of object, M = mass of the earth,r = radius of the earth, G = universal gravitational constant (6.67×10-11 Nm2/kg2)
EXPLANATION:
- As per the above discussion, it's clear that the g value is more at the pole than the equator.
Weight (W) α g
- Mass remains constant always everywhere.
- So weight will be maximum at poles.
- The correct option is 1.
- g is zero at centre of the earth, So the weight of a body at the centre of the earth will be zero.
