Instruction: Please give me at least 3 easy questions, at least 3 medium questions, and at least 3 hard questions. Include the solution and answer in the explanation part.

Tomorrow is our quiz in General Physics 2. I want to practice

Topic: Electric Force and Electric Field

Sample Problems:

(These problems are just sample problems.)

1. Two spheres separated from each other by 10 m have charges of b.1301 C and 0.003 C respectivelv. In between the two spheres is a point of zero electric eld. What is its distance from the 0.901 C sphere? It? points 2. Equal charge of electrons are placed in two spheres 3 cm apart in air. If the resultant force is 4km, how manv electrons does each spheres contain? 5 points 3. Two point charges attract each other with an electric force of magnitude F. if one charge is reduced to one third its original value and the distance between the charges is doubled. what is the resulting magnitude of the electric force between them? It? points 4. Two electrons in a vacuum experience a force of 2 femto-newton. How far apart are the electrons? 3 points 5. A positiver charged dielectric has a charge of 2 C. It 12.5:10\" free electrons are added to it, what will be the net charge on the said electric? 5 points 5. Two point charges of 2 ni: and a 5 n: are 1D micro-meters apart. A third point charge of 5.2 n: is placed between them. At what distance from the 5 nC charge must the third charge is placed, in such a wavthat it will stav in equilibrium? It? points ?. Three equal positive charges of 11554 mi: each are located at the vertices of an equllateral triangle of 2 cm leg. What is the magnitude of the force acting on each charge? Express your answer in giga newtons. ? points
