The charge on each the balloon is 100nC or 1.2 × 10^-7 C
Consider two balloons of diameter 0.200m each with a mass of 1.00g hanging apart with 0.0500m separation on the ends of string making angles of 10.0° with the vertical.
The charge on each balloon can be found from
or 100nC
An electric charge is the property of matter where it has more or fewer electrons than protons in its atoms. Electrons carry a negative charge and protons carry a positive charge. The matter is positively charged if it contains more protons than electrons and negatively charged if it contains more electrons than protons.

Answer:
15km
Explanation:
Given parameters:
Average speed = 60km/hr
Time taken = 15min
Unknown:
Distance = ?
Solution:
The distance traveled can de derived using the expression below;
Distance = Average speed x time taken
Now let us convert the time to hr;
60min = 1hr
15min = = 0.25hr
Distance = 60km/hr x 0.25hr = 15km
