Question 2
A student holds a small positively charged sphere of charge +2.0 × 10⁻⁶ C at rest at point P in a uniform electric field of strength 500 N C⁻¹ directed vertically downward. The student then releases the sphere, allowing it to move 0.15 m downward to point Q. Describe how the electrical potential energy of the charged sphere changes as it moves from P to Q, and explain this change in terms of the electric field strength.
