[8]
ANSWER = "C"
» The acceleration Due to gravity near the moon's surface = 1/6×(near Earth's surface)
===============================
[9]
ANSWER = "A"
» Acceleration = 2×g = 2×9.8 m/s²
=> Acceleration = 2×9.8 = 19.6 m/s²
___________[ANSWER]
===============================
[10]
ANSWER = "B"
the weight of body mass = mass×g = 2×9.8 = 19.6 N
=================================
[11]
ANSWER = "C"
Wight on moon = 1/6×wight on earth
= 120/6 = 20
