The answer to the statement is true because the day is of the logical proportion it has to be time.
Answer:
Weight at the surface of Jupiter's moon Io is 8.13 N .
Explanation:
Given :
Acceleration due to gravity at the surface of Jupiter's moon is
.
Weight of watermelon in earth ,
.
Acceleration due to gravity at the surface of earth is
.
We know , weight is given by :

Therefore , mass at the surface of Jupiter's moon Io is :

Hence , this is the required solution .
The equation for work (W) done by an electric field is:
W = qΔV
where q is the magnitude of the charge and ΔV is the potential difference. The question gives you W and q, so plug n' play to find ΔV:
10 = 2ΔV
ΔV = 5
