Question

A and C please

LUISLOMI IP A charge of 18.04C is held fixed at the origin. If a -6.00 C charge with a mass of 3.00 g is released from rest at the position (0.925 m, 1.17 m), what is its speed when it is halfway to the origin? AED op? Submit Request Answer Part B Suppose the -6.00 C charge is released from rest at the point 0 .9 m) and y (1.17 ). When it is halfway to the origin, is its speed greate than, less than or equal to the speed found in part A? Greater than the speed found in part A Lee than the speed found part in A Equal to the speed found in part A Previous Answers Completed Part C Find the speed of the charge for the situation described in part B. EVO AED – O ?

Answer 1

Solution: 92 = -6.04C P0.925 m, 1.17m) OP=r; 9 = 18.0°C

From work energy theorem, AL = 9192 1 1 478 2 i ?;= (0.925m )2 +(1.17 m) = 1.49m 3(3.0x100kg)(18.04C)(6.04C)(9x109) 1.49 2[18.04C(1050) 6040 ( 10 ) }(9<10) 1.49(3.0x10 kg) =434.899 v=1434.899 = 20.85 m/s 4TTE 0x1 0 kg) v2= (18.0 uc)(6.04C) (9x109) 1.49 2 18.04C10206.04C 1000)) (9x109) v=_ (0.707)(3.0x10 kg) =916.548 v=V916.548 = 30.27m/s
