Question
Three charge are placed are placed at the vertices of an equilateral triangle of side ′a′ as shown in the following figure. the force experienced by the charge placed at the vertex A in a direction normal to BC is :
Options
A.Q2/(4πε0a2)
B.-Q2/(4πε0a2)
C.zero
D.Q2/(2πε0a2)
Solution
Form the figure it is clear that force on Q due to change on B and C will be as shown in the figure. Their resultant will be parallel to BC. Their component perpendicular to BC will be zero.
