Statement I: A spring scale weighing beans in an elevator reads the true weight whether the elevator moves up or down with constant velocity.

Statement II: A beam balance gives the correct mass of the beans even when the elevator accelerates up or down.

Options:

Answer:
A
Solution:

At constant velocity the apparent weight equals .

A beam balance compares two weights and both sides change together in an accelerating elevator, so it still balances at the true mass.

Both statements are true.
