Question

how does the weight of an object change if it is initially weighed at delhi and then taken to the equator

Answer 1

Answer:

The weight of the object will decrease

Explanation:

geff = g - Rw^2cos(theta)

here geff = effective value of acceleration due to gravity.

g= acceleration due to gravity.

R = radius of the earth

w = angular speed of the earth

theta = angle of inclination

here the value of geff at equtor :

geff= g- Rw^2 because here the value of cos theta is maximum that is 1 because here angle is 0 °

the value of geff at poles:

geff = g

because here the value of theta is 90° and therefore the value of cos theta becomes 0.

so here we can conclude that if we take an object from the poles to the equator its weight decreases due to the decrease in the value of acceleration due to gravity.
