Given:
The mass of the tortoise is

The mass of the hare is

The position of the tortoise is

Required:
calculate the position of the hare
Step-by-step explanation:
to calculate the position of the hare we will use the torque concept here that is given as

here r is the position and F is force due
we know that F is force of gravity that is equal to the weight.
rotational equilibrium means that total torque on the system is zero.
then the above relation as

plugging all the values in the above , we get

Thus, the position of the hare is 5 m
