Answer:
0.114m
Explanation:
From the general expression for the radius of the proton's resulting orbit, we have
where q is is the charge of the proton
m is the mass of the proton
B is the magnetic field
and v i the speed.
to determine the speed, we use the expression
Kinetic Energy=
where <em>V </em>is the voltage value i.e 1.0kv
and v is the speed
Hence, from simple rearrangement we have the speed v to be
if we substitute value, we have
carrying out careful arithmetic we arrive at
.
using the value for the speed in the expression for the radius of the orbit as stated earlier, we have
Answer:
D=387.28m
Explanation:
At the moment where the toss is made , so we need both equations:
For the red car:
With initial speed of 0 and acceleration of 6.12m/s^2.
For the green car:
With
and Xo = 200m
Since both positions will be the same:
Solving for t:
t1 = -5.8s and t1 =11.25s
Replacing t = 11.25 on either equation to find the displacement:
