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

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 ? 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

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
