An African fish called the aba has a charge q=+1.3×10−7C at its head and an equal magnitude negative charge −q at its tail, as shown in (Figure 1). The fish and position A are both underwater. Assume the charges to be point-like. Determine the magnitude of the electric field at position A. Determine the magnitude of the force exerted on a hydroxide ion (charge −e) at point A.

Answer #1

The distance from the negative charge to the point A is, d (0.16 m) +(0.12 m) = 0.2 m Find the angle as follows: 0.12 m tan 8

> r2= 0.12 m how can u put this 0.2 m
