We have no idea. There are probably many things involved ... the planet's mass,
the availability of small bodies in the neighborhood that can be captured, etc.
ANSWER and EXPLANATION
We want to identify if there will be an electric field and a magnetic field around the two sticks electrified by charges of opposite signs.
An electric field is a physical field that surrounds electrically charged particles and exerts a force on other charged particles in the surrounding.
This implies that the presence of electric charges on both sticks generates electric fields on them. Since the two charges are opposite, the electric force acting on them will be attractive.
Hence, there is an electric field.
A stationary charged object produces an electric field, as explained above, but will only produce a magnetic field if there is a motion of the object.
Hence, except the two sticks are caused to move, there will be no magnetic field around them.

Answer:
The torque exerted on the merry-go-round is 766.95 Nm
Explanation:
Given;
mass of the merry-go-round, m = 416 kg
radius of the disk, r = 1.7 m
angular speed of the merry-go-round, ω = 3.7 rad/s
time of motion, t = 2.9 s
The torque exerted on the merry-go-round is calculated as;
Therefore, the torque exerted on the merry-go-round is 766.95 Nm
