Question

Which of the two 'g' and 'G' -
(a) is a vector
(b) does not change with the location on the earth's surface.

Answer 1

'G' is the answer...

Answer 2

$\textbf {Diffrence between two}$

g → Acceleration due to gravity
G → Universal Gravitation Constant
____________________________________

(a) $\textbf {Vector Quantity}$
→Quantity which has both magnitude as well as direction.

Since 'g' is Acceleration due to gravity it has both magnitude as well as direction. Hence it is a vector quantity.

(b) Universal Gravitation Constant does not depend on mass or location hece its value remain constant everywhere.
