):


Solution :
Acceleration due to gravity of the earth, g 

Acceleration due to gravity at 1000 km depths is :




= 8.23 m/s
Acceleration due to gravity at 2000 km depths is :




= 6.73 m/s
Acceleration due to gravity at 3000 km depths is :



= 5.18 m/s
Acceleration due to gravity at 4000 km depths is :




= 3.64 m/s
15.49 should be the answer if that is 12 watt battery.
The correct answer to this is (A. Units Only).
It shows that there is a velocity of 35, but the units are missing.
