Answer:
Explanation:
The electric force exerted on a charge due to an electric field is given by:
where
q is the magnitude of the charge
F is the magnitude of the force
E is the magnitude of the electric field
In this problem, we have:
is the charge
is the magnitude of the force
using these data and re-arranging the equation, we can calculate the magnitude of the electric field:

Answer:
Increasing its charge
Increasing the field strength
Explanation:
For a charged particle moving in a circular path in a uniform magnetic field, the centripetal force is provided by the magnetic force, so we can write:
where
q is the charge
v is the velocity
B is the magnetic field
m is the mass
r is the radius of the orbit
The period of the motion is
Re-arranging for r
And substituting into the previous equation
Solving for T,
So we see that the period is:
- proportional to the charge and the magnetic field
- inversely proportional to the mass and the square of the speed
So the following will increase the period of the particle's motion:
Increasing its charge
Increasing the field strength
