The motor branch circuit conductors must have a minimum capacity of 125 percent of motor full-load current to comply with Section 430-22. This results in a minimum conductor ampacity of (1.25 x 16.7) 20.9.
Explanation:
It is given that,
Let are the masses of two objects such that,
............(1)
Force between them,
Distance between masses, d = 19 cm = 0.19 m
The gravitational force between two masses is given by :
.............(2)
On solving equation (1) and (2),
Mass of heavier object,
Mass of lighter object,
Hence, this is the required solution.
