Answer:
b- how much work can be done in a given time
Answer:
there it is fella
And that's according to ma observation
The force on a charged particle on a magnetic field is given by:

where B is the magnitude of the field, q is the charge of the particle, v is its velocity and θ is the angle between the field and the velocity of the particle.
In this case we have that:
• The magnitude of the field is 0.09 T.
,
• The charge of the particle is 3.2 x 10 –19C .
,
• The velocity is 3.0 × 10 4 m/s
,
• The angle between the field and the velocity is 90°, since they are perpendicular.
Plugging these we have:

Therefore, the force on the charge is:
The answer is 2 and 3 because light bulbs dont produce uv rays and uv rays are very dangerous to people.
