Wherever the TV happens to be, its weight is
(mass) · (acceleration of gravity in that place) .
There are small differences, but the acceleration of gravity anywhere on Earth is always close to 9.8 m/s². So if the TV is anywhere on Earth, we can write
147 N = (mass) · (9.8 m/s²)
Divide each sideby 9.8 m/s² : Mass = (147 N) / (9.8 m/s²)
= (147/9.8) kg
= 15 kg .
Not my answer. I got the answer from AL2006 but it is the correct one
