Answer:
distance r from the uranium atom is 18.27 nm
Explanation:
given data
uranium and iron atom distance R = 44.10 nm
uranium atom = singly ionized
iron atom = doubly ionized
to find out
distance r from the uranium atom
solution
we consider here that uranium electron at distance = r
and electron between uranium and iron so here
so we can say electron and iron distance = ( 44.10 - r ) nm
and we know single ionized uranium charge q2= 1.602 × C
and charge on iron will be q3 = 2 × 1.602 × C
so charge on electron is q1 = - 1.602 × C
and we know F =
so now by equilibrium
Fu = Fi
=
put here k = and find r
=
r = 18.27 nm
distance r from the uranium atom is 18.27 nm

Explanation:
The Nucleus: The Center of an Atom. The nucleus, that dense central core of the atom, contains both protons and neutrons. Electrons are outside the nucleus in energy levels.
Answer:
Explanation:
Magnetic field B = 5 x 10⁻³ T
Speed of electron
= ( 5.5 /100) x 3 x 10⁸
= 165 x 10⁵ m /s
Magnetic force on electron
F = Bqv
B is magnetic field , q is charge on electron and v is its velocity
= 5 x 10⁻³ x1.6 x 10⁻¹⁹ x 165 x 10⁵
1320 x 10⁻¹⁷ N
13.2 X 10⁻¹⁵ N
= 13.2 f N
b )
Acceleration = force / mass of electron
= 1320 x 10⁻¹⁷ / 9.1 x 10⁻³¹
= 14.5 x 10¹⁵ m/s²
= 14.5 Pm/s²
c ) The direction of the moving electron will change but its speed will remain constant.
This is so because the magnetic force will be acting perpendicular to the velocity of electron all the time in course of its motion.
