Point charges of 220 acircmicroc and 450 acircmicroc are

Question

Solve the all parts of given question:

Question: Point charges of 22.0 µC and 45.0 µC are placed 0.500 m apart.

Part A: At what point along the line connecting them is the electric field zero?

_____ m (from the smaller charge)

Part B: What is the magnitude and direction of the electric field halfway between them?

______ N/C toward the smaller charge

I would really appreciate some help for above question.
