Round to the hundredths place. 21. A proton is traveling in a magnetic field. The velocity of the proton is 1.87 x 10 m/s and is perpendicular
to the field strength of 1.1 T. What is the radius of the proton traveling in a magnetic field? Put answer in
scientific notation rounding to the ones places (example 5.96e-19 would be 6e-19).

21 protons

Explanation:

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
