Asolid sphere with a radius of 50.0 cm has a total positive charge of 40.0 μc uniformly distributed in its volume. calculate the magnitude of the electric field 10.0 cm away from the center of the sphere:

a

1.8e+008 n/c

b

3.2e+004 n/c

c

1.44e+010 n/c

d

2.880e+005 n/c

Explanation:

It is given that,

The radius of the solid sphere, R = 50 cm = 0.5 m

Charge on the sphere,

We need to find the magnitude of the electric field r = 10.0 cm away from the center of the sphere. The electric field at point r away form the center of the sphere is given by :

So, the electric field 10.0 cm away from the center of the sphere is . Hence, this is the required solution.              

answer: a. same unit

explanation:
