Answer:

The gravitational force between proton and an electron is 4.06 \times 10^{-47} N

Explanation:

Given:

Mass of proton m_{1} = 1.67 \times 10^{-27} kg

Mass of electron m_{2} = 9.11 \times 10^{-31} kg

Separation between electron and proton r = 5 \times 10^{-11} m

According to the gravitational law,

   F = \frac{Gm_{1} m_{2}  }{r^{2} }

Where G = 6.674 \times 10^{-11} = gravitational constant.

   F = \frac{6.674 \times 10^{-11} \times 1.67 \times 10^{-27} \times 9.11 \times 10^{-31}   }{(5 \times 10^{-11} )^{2} }

   F = 4.06 \times 10^{-47} N

Therefore, the gravitational force between proton and an electron is 4.06 \times 10^{-47} N

A worker pushes a box with a horizontal force of 40.0 N over a level distance of 4.0 m. If a frictional force of 27 N acts on th
Lorico [155]

Work = (force) x (distance)

The worker does  (40N) x (4m) = 160 joules of work.

Friction eats up    (27N) x (4m) = 108 joules of that energy,
                                                         generating 108  joules of heat.                         

The remaining    (160J - 108J) = 52 joules of energy moves the box.
