Which outcome would validate Einstein’s equivalence principle experientially during freefall?

A)Observer sees only gravitational effects
B)Constant proper acceleration is always felt
C)Electrogravitic forces maintain constant levels
D)Inertial mass varies with observer frame

💡 Explanation

The absence of perceived gravity supports equivalence principle because gravitational acceleration and inertial acceleration offsets due to freefall neutralize one another; therefore only inertial effects vanish, rather than differing effects correlating to acceleration.
