question 50

Multiple Choice

Four tiny charged particles (two having a charge $+ Q$ and two having a charge $- Q$ ) are distributed on the $x$ - and $y$ -axes as shown in the figure. Each charge is equidistant from the origin. In which direction is the net electric field at the point $P$ on the $y$ -axis?

• A) upwards and towards the left
• B) directly left ( \(- x\) direction)
• C) upwards and towards the right
• D) directly up (in the \(+ y\) direction)
