Question

1)Two point charges lie on the x-axis. A charge of +7.7 C is at the origin, and a charge of -5.4 C is at x = 10.0 cm. (a) At what position x would a third charge q3 be in equilibrium?

2) An object of mass m = 3.6 g and charge Q = +44 C is attached to a string and placed in a uniform electric field that is inclined at an angle of 30.0 with the horizontal. The object is in static equilibrium when the string is horizontal.

(a) Find the magnitude of the electric field.

(b) Find the tension in the string.

I will raise the points if both questions were answered correctly

1)Two point charges lie on the x-axis. A charge of +7.7 ½C is at the origin, and a charge of -5.4 ½C is at x = 10.0 cm. (a) At what position x would a third charge q3 be in equilibrium? 2) An object of mass m = 3.6 g and charge Q = +44 ½C is attached to a string and placed in a uniform electric field that is inclined at an angle of 30.0½ with the horizontal. The object is in static equilibrium when the string is horizontal. (a) Find the magnitude of the electric field. (b) Find the tension in the string. I will raise the points if both questions were answered correctly
