three rigid rods are joined to form an equilateral triangle ABC of side 1m . three particles carrying charges 20 micro coulomb each are attached to the vertices of the triangle.  the whole system is at rest in inertial frame .  the resultant force on the charged particle a has the magnitude ?
ans= zero

charged particles are on vertices

force on vertex A wont be 0 it will be 2k q square / r square         X         cos 30

a)  zero
b)3.6N
c)3.6*square root of 3
d)7.2N
 
ANS IS OPTION  A  &  NO FIGURE IS GIVEN &  I HAVE WRITTEN EXACT QUES WOR TO WORD

ans c ) 3.6 * root 3 ..... many answers in hc verma are often wrong.

see figure... now put values. k = 9 X 10^9 , q = 20 X 10^ -6 , cos 30 = root 3  /   2
 
and u get F net on A = 3.6 * root3 N
