Two point masses

m_1 = 1\,\text{kg}

and

m_2 = 4\,\text{kg}

are fixed

30\,\text{cm}

apart on a straight line. At what distance from the

1\,\text{kg}

mass, along the line joining them, is the net gravitational field intensity zero? a)

15\,\text{cm}

10\,\text{cm}

6\,\text{cm}

20\,\text{cm}
