Answer:
Option (2) is g. It is gravitational field strength
Step-by-step explanation:
The gravitational field strength is defined as the gravitational force per unit mass. It is given by :
Where
F is the gravitational force
m is the mass
Option (1) is
. It is the force of gravity
Option (2) is g. It is gravitational field strength
Option (3) is G. It is universal gravitational constant
Option (4) is
. It is centripetal force
So, the correct option is (C) "g". Hence, this is the required solution.
