Answer:
a) 120 N
b) 5 N
c) 0.2 N
d) Mass remains the same, and weight decreases.
Explanation:
Use the formula W = mg, where mass is in kg, and gravitational field strength in N/kg.
a)
W = mg
= 12 × 10
= 120 N
b)
500 g = 0.5 kg
W = mg
= 0.5 × 10
= 5 N
c)
20 g = 0.02 kg
W = mg
= 0.02 × 10
= 0.2 N
d)
Mass remains the same, and weight decreases.
