We have to
m = 65 kg
r = 0.85 m
t = 2.3 s
The perimeter of the circle is given by:
P = 2 * pi * r
P = 2 * pi * (0.85 m)
P = 5.34 m
Then, by definition, the distance equals the speed by time:
d = v * t
v = d / t
v = (5.34 m) / (2.3 s)
v = 2.32 m / s
Then, to find the radial acceleration, we must use the speed found and the radius of the circle:
a = v ^ 2 / r
a = (2.32 m / s) ^ 2 / (0.85 m)
a = (5.38 m ^ 2 / s ^ 2) / (0.85 m)
a = 6.32 m / s ^ 2
Finally, we have that by definition the force is equal to the mass by acceleration:
F = m * a
F = (65 kg) * (6.32 m / s ^ 2)
F = 410.8 N
answer
F = 410.8 N

Answer:
In physics, a charged particle is a particle with an electric charge. ... It can also be an electron or a proton, or another elementary particle, which are all believed to have the same charge (except antimatter). Another charged particle may be an atomic nucleus devoid of electrons, such as an alpha particle. Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
