Answer:
16.9000000000000001 J
Explanation:
From the given information:
Let the initial kinetic energy from point A be
= 1.9000000000000001 J
and the final kinetic energy from point B be
= ???
The charge particle Q = 6 mC = 6 × 10⁻³ C
The change in the electric potential from point B to A;
i.e. V_B - V_A = -2.5 × 10³ V
According to the work-energy theorem:
-Q × ΔV = ΔK
