The correct answer should be 2.6 billion years (if i am correct)
Answer:
option (b)
Explanation:
Let the electric field is given by E.
mass of proton = mp
mass of electron = me
acceleration of proton = ap
acceleration of electron = ae
Charge on both the particle is same but opposite in nature.
The force on proton = q E
The force on electron = - q E
acceleration of proton, ap = q E / mp
acceleration of electron, ae = - q E / me
We observe that the force is same in magnitude but opposite in direction, acceleration is also different and opposite in direction.
The heat Q transferred to cause a temperature change depends on the magnitude of the temperature change, the mass of the system, and the substance and phase involved.

Answer
given,
radius of the circular orbit, r = 0.53 x 10⁻¹⁰ m
mass of electron, M = 9.11 x 10⁻³¹ Kg
charge of electron, q₁ = 1.6 x 10⁻¹⁹ C
q₂ = 1.6 x 10⁻¹⁹ C
we know, force between two charges
F = 8.20 x 10⁻⁸ N
b) using newton's second law
F = m a
m a = 8.20 x 10⁻⁸
a = 9 x 10²² m/s²
c) speed of the electron
v² = 4.77 x 10¹²
v = 2.18 x 10⁶ m/s
d) the period of the circular motion.
T = 1.53 x 10⁻¹⁶ s
