Charges 4Q, q and Q are placed along x-axis positions x=0, x= (l)/(2) and x=l respectively. The value of q so that the force on charge Q is zero is

Point charges +4q, -q and +4q are kept on the x-axis at points x=0,x=a and x=2a respectively, then

Point charges +4q, -q are kept on the x -axis at points x=0,x=a and X=2a respectively, then

Point charges + 4q, -q and +4 q are kept on the X-axis at points x = 0, x = a and x = 2 a respectively

Three charges 4q , Q and q are in a straight line in the position 0, l/2 and l respectively. The resultant force on q will be zero if Q is equal to

Two charges q_1 and q_2 are placed on the X-axis at point x=-a and x =+a respectively. a. How must q_1 and q_2 be related for the net electrostatic force on a charge Q at x= +(a)/(2) to be zero? b. Repeat (a) but with +Q at x =+ (3a)/( 2)
