Explanation:
Since the two charged bodies are symmetric, we can calculate the electric field taking both of them as point charges.
This can be easily seen if we use Gauss's law,
We take a larger sphere of radius, say r, as the Gaussian surface. Then the electric field due to the charged sphere at a distance r from it's center is given by,
which is the same as that of a point charge.
In our problem the charges being of opposite signs, the electric field will add up. Therefore,
where, = distance between the center of one sphere to the midpoint (between the 2 spheres)
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
