(1) Consider two point charges of magnitude q/2 separated by distance R and held in relative position by a massless rod. An identical massless rod with the same charges lies a distance R away, in the same plane, parallel, q and with centers aligned. I guess you better see the drawing! 2 By dimensional analysis, the force between these two objects must be some factor times kq2/R2, in other words: kq2 Find the factor C.
Two point charges q and ?q are separated by a distance L. What is the magnitude of the force on a third point charge q placed at the midpoint between them? (a) 8kq2/L2 (b) 2kq2/L2 (c) 0 (d) 4kq2/L2 (e) kq2/L2 any explanation is helpful!
Two point charges, Q1 and Q2, are separated by a distance R. If the magnitude of both charges are tripled and their separation is also tripled, what happens to the magnitude of the electrostatic force that each charge exerts on the other. A. It decreases by a factor of 3 1/2 B. It increases by a factor of 9 C. It stays the same D. It increases by a factor of 3 E. It increases by a factor of 3...
Two point charges are separated by a distance r. If the separation is reduced by a factor of 3.6, by what factor does the electric force between the two charges increase?
Two point charges are separated by a distance r. If the separation is reduced by a factor of 2.9, by what factor does the electric force between them change?
2, An electric dipole consists of charges+q separated by a distance d and aligned along the z- axis Show that the potential due to this dipole at points far from the dipole (i.e. r od) is approximately qd cos θ
If two equal positive charges are separated by a distance r and then they are moved so that their separation distance doubles, what happens to the electrical potential energy stored in the system? which answer is right: ??? A. Increased by a factor of 4 B. Increased by a factor of 2 C. Decreased by a factor of 2 D. Decreased by a factor of 4
5. Two point charges +Q and -Q are separated by a distance D and fixed in place. You then bring in from very far away a third point charge q to form an equilaterial triangle (i.e., all lengths are D). In doing so, you have: A. Increased the potential energy if q < 0; decreased it if q > 0. B. Increased the potential energy of the system. C. Not changed the potential energy of the system D. Increased the...
Two identical particles, each having charge +q, are fixed in space and separated by a distance d. A third particle with charge -Q is free to move and lies initially at rest on the perpendicular bisector of the two fixed charges a distance x from the midpoint between those charges (see figure below). tq -Q a) Show that if х ıs small compared with d, the motion of Q is simple harmonic along the perpendicu arbi sector.
