You are exploring a newly discovered planet. The radiusof the planet is 7.20 * 107 m. You suspend a lead weight from thelower end of a light string that is 4.00 m long and has mass 0.0280 kg.You measure that it takes 0.0685 s for a transverse pulse to travel fromthe lower end to the upper end of the string. On the earth, for the samestring and lead weight, it takes 0.0390 s for a transverse pulse to travelthe length of the string. The weight of the string is small enough thatyou ignore its effect on the tension in the string. Assuming that the massof the planet is distributed with spherical symmetry, what is its mass?

Question

You are exploring a newly discovered planet. The radius
of the planet is 7.20 * 107 m. You suspend a lead weight from the
lower end of a light string that is 4.00 m long and has mass 0.0280 kg.
You measure that it takes 0.0685 s for a transverse pulse to travel from
the lower end to the upper end of the string. On the earth, for the same
string and lead weight, it takes 0.0390 s for a transverse pulse to travel
the length of the string. The weight of the string is small enough that
you ignore its effect on the tension in the string. Assuming that the mass
of the planet is distributed with spherical symmetry, what is its mass?
