The centripetal force : F = 293.3125 N
<h3>Further explanation</h3>Given
mass = 65 kg
v = 9.5 m/s
r = 20 m
Required
the centripetal force
Solution
Centripetal force is a force acting on objects that move in a circle in the direction toward the center of the circle
F = centripetal force, N
m = mass, Kg
v = linear velocity, m / s
r = radius, m
Input the value :
F = 65 x 9.5² / 20
F = 293.3125 N
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
