What is the potential difference V?

3. A helium nucleus is accelerated from rest through a potential difference V to a kinetic energy of X ∙ 10⁻¹³ J. 
What is the potential difference V?
X is some number.

Answer:


V = E/q = E/(2e) = X ∙ 10⁻¹³ J / (2∙1.60×10⁻¹⁹ C) = 0.312X MV

What is the electric flux through an area?

2. A thin spherical shell of radius x₁ cm has x₂ µC of charge uniformly distributed over its surface. What is the electric flux through an area of x₃ m² of a spherical surface concentric with the shell of charge but having a radius of x₄ m?
x₁, x₂, x₃, and x₄ are some numbers.

Answer: 8.99∙10⁴∙ x₂ ∙ x₃ / x₄² N∙m²/C
