Suppose an electron is moving with a constant velocity until it encounters a positively charged sphere on its right. how does the sphere alter the trajectory of the electron?

a. it has no effect on the trajectory of the electron
b. it deflects the electron to the right.
c. it deflects the electron to the left.
d. impossible to tell

b. It deflects the electron to the right.

Explanation:

Since the sphere is positively charged and electron has negative charge, it will be attracted toward the sphere and hence,

The electron is deflected to the right as the positively charged sphere on its right

So, the 2nd option is correct.
