A) 0.23 N in the +x-direction
B) 0.46 N in the +x-direction
C) 0.23 N in the +x-direction
D) 0.46 N in the +x-direction
Correct Answer: B
Solution :
[b] \[{{F}_{net}}=2|{{F}_{31}}|cos\alpha \] \[=2\times \frac{1}{4\pi {{\varepsilon }_{0}}}\times \frac{2\times 4\times {{10}^{-12}}}{{{\left( 0.5 \right)}^{2}}}\times \frac{4}{5}=0.46N\]You need to login to perform this action.
