A particle of unknown charge Q and unknown mass M enters a region of uniform mag

Question

A particle of unknown charge Q and unknown mass M enters a region of uniform magnetic field with a known velocity. Which quantities may be determined by examining the path that the particle follows? A. |Q| and M. B. Sign of Q and M. C. Q/M. D. Q/M and sign of Q. E. |Q|, sign of Q, and M. 6. A circuit is shown in the figure below. Which choice represents a correct application of Kirchhoff's Loop Rule to one loop in this circuit, where currents are assumed to travel in the indicated direction? A. +epsilon_2 + I_2r_2 - I_3R_3 + I_2R_2 = 0 B. +epsilong_2 - I_2r_2 - I_3R_3 - I_2R_2 = 0 C. +epsilon_2 + I_2r_2 + I_3R_3 + I_2R_2 = 0 D. +epsilon_2 - I_2r_2 + I_3R_3 - I_2R_2 = 0

Explanation / Answer

5) It will be D

That is charge to mass ratio and sign of q

6) Applying KVL in loop on right it will be option C
