Question

If this answer is in scientific notation, please provide the decimal answer to the nearest 4 decimal places. My NotesO Ask Your Teacher /1 points OSColPhys2016 18.3P 020 Common transparent tape becomes charged when pulled from a dispenser. If one piece is placed above another, the repulsive force can be great enough to support the top piece's weight. Assuming equal point charges (only arn approximation), calculate the magnitude of the charge if electrostatic force is great enough to support the weight of a 5.00 mg piece of tape held 1.50 cm above another. (The magnitude of this charge is consistent with what is typical of static electricity.)

Explanation / Answer

According to the given problem,

Let the charges be modeled as point particles

Electric force between the charges , F = kq2/r2  where q = charge, r = 1.150 cm.

Now, to support the tape, force of gravity must be same as electric force

F = mg where m = 5mg = 5*10-6 kg

So, kq2/r2 = mg

So, q = (mgr2/k)

q = (5*10-6*9.81*0.0152/(8.99*102))

q = 1.10797*10-9 C.

I hope you understood the problem, If yes rate me!! or else comment for a better solution.
