Identify the given values: current (I) is 3 × 10^4 A and time (t) is 50 ms.
Convert the time from milliseconds to seconds: 50 ms = 50 × 10^-3 s.
Use the formula for charge (Q) which is Q = I × t, where I is the current and t is the time.
Substitute the given values into the formula: Q = (3 × 10^4 A) × (50 × 10^-3 s).
Calculate the product to find the total charge that enters the ground.
