The Lorentz force exerted on a charge moving in a magnetic field is given by:
where
q is the charge
v is the speed of the charge
B is the intensity of the magnetic field
is the angle between the directions of the field and of the velocity
The data we have in our problem are:
If we substitute these data and we rearrange the initial equation, we can calculate the speed of the particle:
so, the correct answer is
<span>1.1 × 104 m/s</span>
Explanation:
weight=mass ×acceleration
weight=25×9.8
=245

Answer:
the acceleration of the car is -5 m/s².
Explanation:
Given;
initial velocity of the car, u = 50 m/s
time of motion, t = 6 s
final velocity of the car, v = 20 m/s
The acceleration of the car is calculated as;
Therefore, the acceleration of the car is -5 m/s².
I think the answer is B 1:100
