Unformatted text preview: 5 6 7 4. 9.6x10^ 16 # N 8 5.A uniform electric field of 300N/C makes an angle of 25 q with the dipole moment of an electric dipole. If the torque exerted by the field has a magnitude of 2.5x10-7 N m, what must be the dipole moment? F + E u G G G 7 in scalar form sin (2.510 ) pE pE Nm W W T W u F 9 ( ) 2.010 sin (300/)sin25 p Cm E N C T x axis 9 6. Positive charge Q is distributed uniformly throughout an insulating sphere of radius R, centered at the origin. A particle with positive charge Q is placed at x = 2R on the x axis. What is the ma gnitude of the electric field at x = R/2 on the x axis? g x R E S E P 3 2 At x=/2 charged insulating sphere generates electric field Q = directed to the positive direction of x axis 2 8 S R Q R E R 4 2 8 A particle with a positive charge Q placed at a ditance 3/2 from x=/ o o R R R R S H S H 2 generates electric field directed to the negative direction of x axis with a magnitude Q Q 2 2 9 3 4 2 The resultant electric field at x=/2 is directed to the positive direction of x axis p o o E R R R S H S H Q 10 an 2 2 2 Q d has magnitude of 8 9 7 2 o o o Q Q E R R R S H S H S H 7. 7....
