Answer:
Will experience a force due to electric field.
Explanation:
- When a free negative charge is released in an electric field it experiences a force due to the electric field in a direction opposite to the direction of the magnetic field.
According to Coulomb's law this force is mathematically given as:

and, electric field due to a charge is given as:

where:
permittivity of free space
q = magnitude of charge
r = radial distance from the charge
Answer:
300J
Explanation:
Given parameters:
Constant force = 15N
Distance = 20m
Unknown:
Work done = ?
Solution:
Work done is the force applied to move a body through a particular distance.
Work done = Force x distance
So;
Work done = 15 x 20 = 300J
Answer:
d satellite i think
Explanation:
i eliminated all the other answers, when i notice that Orbit, Period, and Rotation are not Bodies.
The average velocity of the beetle is equal to the ratio between the displacement and the time:

The displacement of the beetle is

The time is t=12.8 s
Therefore, the average velocity is

in the positive x-direction.
