Answer:
F = 1.608 x 10⁻¹⁴ N
Explanation:
Given,
The velocity of the electron, v = 10⁷ m/s
The electric field intensity, E = 10⁵ V/m
The magnetic flux density, B = 0.5 gauss
= 5 x 10⁻⁵ tesla
The magnitudes of the electric and magnetic forces on an electron is given by the Lorentz force,
F = q (E + v x B)
Substituting the given values,
F = 1.6 x 10⁻¹⁹ (10⁵ + 10⁷ x 5 x 10⁻⁵)
F = 1.608 x 10⁻¹⁴ N
Hence, the magnitudes of the electric and magnetic forces on an electron is, F = 1.608 x 10⁻¹⁴ N
Answer:
energy from excess mass
Explanation:
The correct answer for the given question out of the given options is the option " energy from excess mass ".
This happens due to the fact that some of the matter is converted into the energy during the fusion of atoms.
The relation that can be stated is E = mc²
where,
E is the energy
c is the speed of the light
m is the mass of the matter
