A wooden block of mass m1 kg accelerates at m/s when a force of 5 N acts on it. Another block of mass m2 kg accelerates at 20 m/s when the same force acts on it. If both the blocks are tied together and the same force acts on their combination, the acceleration will be about

Consider a hypothetical planet with a mass equal to half that of Earth and radius is one-third that of Earth. If g is the acceleration due to gravity on Earth, the acceleration due to gravity on the planet will be
