A charged oil drop that carries 14.4 x 10-13 C of charge and has a mass of 2 x 10-4 kg is released from a location in between two identical large charged spheres, that is a distance 3 cm from the first large sphere's center demonstrated below. If both spheres have Qsphere = 8 me each and separated by distance of 15 cm from each others centers, (a) find the acceleration of the oil drop at the moment of it's release (b) find the velocity of the oil drop after it traveled 1 cm toward the (first or second?) sphere Ignore gravitational pull by Earth Use may use the following constants: k: 8.88 x 109 N m2102 , 88 = 8.854 x 10-12 C2/Nm2 m (milli) = 1o~3 oil drop Sphere 1 Sphere 2 +X
