a student applies a constant 200 n of force horizontally to a box for distance of 5.0 m. how much work does the student do on the box?

W = (2.0 N) * (4.00 m) * cos (60 degrees) = 4.0 J

Explanation:

Its not just a mere formula . It tells a hell lot about charges .

q = ne . As you know , q stands for charge and e stands for charge on an electron . As for n , it represents an integer.

This whole q=ne thing represents quantisation of charge. The formula tells us that charge is quantized ( in the form of small packets)

Every body on this small earth has a charge which has to be an integral multiple of ‘e’ . So , we represent charge on a body(q) as

q=ne.

Hence the formula .

I hope you got what I want to say .
