Spacecraft have been sent to mars in recent years mars is

Question

Problem: Spacecraft have been sent to Mars in recent years. Mars is smaller than Earth and has correspondingly weaker surface gravity. On Mars, the free-fall acceleration is only 3.8m/s².

Part A: What is the orbital period of a spacecraft in a low orbit near the surface of Mars?

I want help to find the orbital period of a spacecraft in a low orbit near the surface of Mars and assume the radius of the satellite's orbit is about the same as the radius of Mars itself, rMars= 3.37 x 10⁶ m.
