What are the correct units for this equation: GPE = mass x gravitational field strength x height *

1 point

GPE (J) = mass (Kg) x gravitational field strength (m/s) x height (m)

GPE (J) = mass (N) x gravitational field strength (m/s2) x height (m)

GPE (m) = mass (Kg) x gravitational field strength (m/s2) x height (N)

GPE (W) = mass (Kg) x gravitational field strength (m/s2) x height (m)

GPE (J) = mass (Kg) x gravitational field strength (m/s2) x height (m)
