Problem 10-31(a) Vector electric field - Part 2 - D

The figure shows the positions of two a particles (charge on each is $+2e$) and an electron. What are the magnitude and direction of
(a) the resultant force on the electron?
(Hint: choose the $+x$ axis along the line from the electron to the right-hand a particle.)

[Ans.(a) $1.31 \times 10^{-8} N$ at $13.3^\circ$ to left of line from electron to right-hand a]

Accumulated Solution

No. The electron and the $\alpha$ particle are a case of unlike charges ($e -$) ($\alpha +$). Unlike charges attract or do they repel?

Choose one.
