Question

iectric dipole is released from rest in a uniform electric ficld with the orientation shown. Which one(s) of the following statements is/are true? F=q6 ma-aE E a. The electric dipole experiences an initial linear acceleration proportional to 20E; b. The electric dipole experiences an initial angular acceleration proportional to QEd The electric dipole is in translational equilibrium d. The electric dipole is in rotational equilibriume The electric dipole is in static equilibrium 14. Two charges (qi and q2) of same sign are separated by a distance R, The System has potential energy Ue (U 0 when R-ao), determine which of the following changes results in increasing the Potential Energy of the U-K 99 system. Tripling the magnitude of each charge and changing their signs; bDecrease the distance between the two charges to R/2 while doubling their charge. Changing the sign of one charge and decreasing the distance to R/3; Double both charges, change the sing of qi and set the distance between them to 3R; e. Decreasing the distance between them to R/4 and decreasing the magnitude of each charge in half.x R/A 309 U 99 15. The figure illustrates three charges of magnitude Q represented with numbers 1, 2, and 3, the field lines, and the shade area is a Gaussian surface. Which one(s) of the following statements is/are true about the V=499 situation? 3R U99 RIS All charges have the same sign; a. The electric flux through the Gaussian surface is zero; Charge 2 has the opposite sign of 1 and 3; 20 d. The electric flux through the Gaussian surface is . The resulting electrostatic force on charge 2 is directed towards 1.
