Two charges`+q_(1)` and `-q_(2)` are placed at A and B respectively. A line of force emanates from `q_(1)` at an angle `alpha` with the line AB. At what angle will it terminate at `-q_(2)` ?

Three charges -q_(1), +q_(2) and -q_(3) are placed as shown in the figure. The x -component of the force on -q_(1) is proportional to

Three charges -q_(1), +q_(2) and -q_(3) are placed as shown in the figure. The x -component of the force on -q_(1) is proportional to

Two points charge q_(1) and q_(2)(=q_(1)//2) are placed at points A(0,1) and B(1,0) as shown in the figure.The electric field vector at point P(1,1) makes an angle q with the x-axis ,then the angle q is

Three charges -q_(1), + q_(2) and -q_(3) are placed as shown in the figure. The x - component of the force on q_(1) is proportional 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)
