Answer 1

Answer:

0.40 N

Explanation:

On Earth:

= > weight = mass * gravity

= > 6 N = mass * 9.8 m/s²

= > 6/9.8 kg = mass

On Pluto: Acceleration of free fall is 0.66 m/s²

Means, on Pluto, gravity is 0.66 m/s²

There,

= > weight = mass * gravity

= > weight = (6/9.8) * (0.66) N

= > weight = 0.40 N

Correct option is B

Answer 2

Given ,

• The weight of an object is 6 N

• The acceleration of free fall on pluto is 0.66 m/s²

We know that , the weight of a body is given by

$\boxed{ \sf{Weight = Mass \times Acceleration }}$

Thus , the mass of object on earth

6 = Mass × 9.8

Mass = 6/9.8 kg

Now , the weight of object on pluto will be

Weight = (6/9.8) × 0.66

Weight = 0.40 N

∴ The correct option is (B) i.e 0.40 N
