Question 1 2 pts Find the magnitude of the net force on the rightmost charge. q= 2 x 10-6 c, d = 1cm + + -a 2d 1-1++-.png O a) 50N Ob) 130N O c) 320N O d) 2500N

Answer 1

D. 3d=3cm +2. - to 2d=2cm Electric force blu two charges, a, and a F = k 9,22 r² k= coulumb's constant r= Distance blu charges. a positive and a negative charge is left. force b/w atractive. so in the given the given problem both (+9) charges will attract (-9) toward so total magnitude of force -2 charge is of magnitudes of forces acting due to each tq charge. for left most charge and right most charge, Sapration r = 3cm - 3810-2 m on sum on rq charge

for centure and rightmost charges, saperation a dz=2cm = 2x10-2 m So, from ① and @ Net force on charge (-2) = F = kaq k 29 + 8,2 r² 9x109 x 2x 106 x 2x10-6 9 + (3 x102) ? 940" x 240 x 2x10-6 (x10-2)2 - E= 36x103 + 9 x 10-4 36x10-3 4X10-4 ch => F=uX10 + 9810 => F=130N

on ) 2 Direction of of force rightmost charge is left because force blo a positive and negative charge is force. a an attractive an connected 6) Voltmeter have infinite susistance and ammeter have nearly zero resistance. in figure (6) ammeter is power supply, directly with in series with ammeter. son the ammeter have nearly 2010 riesistance, so current in ammeter will be infinte ou very large. which will damage the ammeter. to any resistance since
