(a) calculate the electric field strength near a 10.0 cm diameter conducting sphere that has 1.00 c of excess charge on it. (b) what is unreasonable about this result? (c) which assumptions are responsible?

Electric field strength near the surface of sphere is given by

Now we have

Q = 1 C

R = 5 cm

now electric field is given by

Part B)

Since charge on the sphere is very large to electric field near its surface is too high. So this is reasonable result near it.

Part c)

As per our assumption the charge is uniformly distributed on the surface and there is no effect of surrounding charge or surrounding electric field.

are there options? cause you ain’t. real specific

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
