three charges of 2mC ,-4mC and -4mC are kept at vertices of euilateral traingle of side 10 cm . a charge q is kept on the mid point of -4mC and -4mC charge.calculate the value of q such that 2mC charge remains in equilbrium.

Question

Khimraj · Answer

net force on 2mC = 0 so 2*(K*2mC*(-4mC)/0.1 2 )cos30 + K*2mC*q/(3*0.1 2 /4) = 0 -8mC*cos30 = -4q/3 q = 6mC*cos30 = 3mC Hope it clears............................
