force acting on the ball
1) electric force
2) tension
3) weight
T + qE = mg
45 + 0.03*E = 6.12*9.8
E = 499.2 N/C
so the value of electric field is 499.2N/C

Constant:s VPart A A point charge of mass 0.235 kg, and net charge +0.355 C, hangs at rest at the end of an insulating cord above a large sheet of charge. The horizontal sheet of fixed uniform charge creates a uniform vertical electric field in the vicinity of the point charge. The tension in the cord is measured to be 4.80 N Determine the direction of the electric field due to the sheet of charge (see (Figure 1)) upward downward...

A positive charge with a mass of 4 kg is placed on a string and a negative charge of the same amount (magnitude) but negative is placed directly to the right of this charge when in equilibrium. Also, the angle with the vertical of the string is 43.31 degrees when the charge is in equilibrium. Then the negative charge is moved directly below the charge on the string and it is placed twice as far as it originally was to...
Question 4 (STPM Question): A small positive charged sphere with mass 0.8 g suspended by a light string from the ceiling in an electric field of intensity 900 NC,is shown in the diagram below. 130 In the equilibrium position shown, the string makes an inclined angle of 30° with the vertical line.
