2. Four charges are fixed in place on a line and adjacent charges are equally separated by a distance d = 2.5 m as shown in the figure below. The are q₁ = 1.0 x 10-5 C, 92 = -3.0 x 10-5 C, q3= -4.6 × 10- C, and charges are 943.2 x 10-5 C. (a) Calculate the net force (magnitude and direction) on charge q. (b) Calculate the net force (magnitude and direction) on charge 92. 91 do bid bord 93 92 94

Two identical conducting spheres are charged with a net charge of +2.0 q on the first sphere and a net charge of -4.0 q on the second sphere. The spheres are brought together, allowed to touch, and then separated. What is the total charge on the two spheres? a. +6.0 q b. +2.0 q c.-2.0 q d. -6.0 q  e. None of the above

Two charges, q1=-0.3mC and q2=--1.94mC are placed 12.02m apart from one another (mC stand for "milli-Coulomb").  What is the the electric force that q2 experiences due to the presence of q1?  Note, if the force direction is "to the left" be sure to include a negative sign.  If the direction of the force is "to the right", the force should be positive in sign.

An object has an excess charge of -1.6 x 10 1 C. How many excess electrons does it have?

Two protons in a molecule are 3.90  10-10 m apart.  What must be a particle's charge-to-mass ratio if the magnitude of the gravitational force between two of these particles is equal to the magnitude of electric force between them? C/kg

Two objects charged with an equal amount of charge interact with each other with a force of 4.81 Newton when separated by a distance of 16.9 cm. Determine the magnitude of the charge on each object. Answer:_______x10-6 C Enter only the coefficient of the scientific notation. For example, you'd enter just just 1.27 if you get 1.27x10-⁹.
