Answer:
0
Step-by-step explanation:
Joe had 5 and Mary had 5.
The amount each person has is equal. They don't have more or less than each other. So it's 0.
The charge of the electrons is 
.
The given parameters:
- <em>Number of revolution of the electron, N = 1.4 x 10⁶ rev per sec</em>
- <em>Flux density, B = 10⁻⁵ T</em>
- <em>Mass of electron, m = 9.11 x 10⁻³¹ kg</em>
<em />
The angular speed of the electron is calculated as follows;
The charge of the electrons is calculated as follows;
The charge of the electrons is .
The complete question here:
Electrons execute 1.4*10^6 revolutions per sec in a magnetic field of flux density 10⁻⁵ T. What will be the value of charge of the electron?

Significant figures tells us that about how may digits we can count on to be precise given the uncertainty in our calculations or data measurements.
Since, one inch = 2.54 cm.
This is equivalent as saying that 1.0000000.. inch = 2.540000... cm.
Since the inch to cm conversion doesn't add any uncertainty, so we are free to keep any and all the significant figures.
Since, being an exact number, it has an unlimited number of significant figures and thus when we convert inch to cm we multiply two exact quantities together. Therefore, it will have infinite number of significant figures.
784.5+(784.5×0.065)
=784.5+50.9925==835.4925 round the answer=835.5
