Question
Acharge q isplaced on the x-axis at x:-1.00 meters. A uniform line of charge with charge density ?-+200 cim lies on the x-axis from x-1.0 shown. tox-200 meters as +2.00 HC/m -1.00 x=900 x= +1.00 x-+2.00 Part A (7 points) Determine the total electric field produced by the charge and uniform line of charge at the origin (x-o). Submit Request Answer ? Part B (3 points) Find the acceleration (magnitude and direction) that would be experienced by a small 2.5-gram sphere with a charge of 0.55 mC that is located at the origin.Explanation / Answer
electric field due to the rod,
E_rod = k*lamda*(1/1 - 1/2)
= 9*10^9*2*10^-6*(1 - 1/2)
= 9000 N/c
Eq = k*q/r^2
= 9*10^9*1.5*10^-6/1^2
= 13500 N/c
A) Enet = Eq - Erod
= 13500 - 900
= 12600 N/c
B) use, F = q*Enet
m*a = q*Enet
a = q*Enet/m
= 0.55*10^-3*12600/(2.5*10^-6)
= 2.78*10^6 m/s^2
