An insulating rod having linear charge density λ = 40.0 mC/m and linear mass density μ = 0.100 kg/m is released from rest in a u
niform electric field E = 100 V/m directed perpendicular to the rod.
(a) Determine the speed of the rod after it has traveled 2.00 m.
(b) What If
(a) Determine the speed of the rod after it has traveled 2.00 m.
(b) What If
1 answer:
Answer:
a) Speed of the rod = 0.4m/s
b) The part b says what if ? how does your answer to part (a) change if the electric field is not perpendicular to the rod?
If the electric field is not perpendicular to the rod, then a rrsolution has to be don eon the x -axis by resolving with respect tp Cos theta, the value pf the speed will still remains the same.

Answer:
The energy of an electron in an isolated atom depends on b. n only.
Explanation:
The quantum number n, known as the principal quantum number represents the relative overall energy of each orbital.
The sets of orbitals with the same n value are often referred to as an electron shell, in an isolated atom all electrons in a subshell have exactly the same level of energy.
The principal quantum number comes from the solution of the Schrödinger wave equation, which describes energy in eigenstates , and for the case of an hydrogen atom we have:
Thus for each value of n we can describe the orbital and the energy corresponding to each electron on such orbital.
