http bin/orielly/cap: c capa e gryphon.plhy.umassd.edu x ]capesbin G Google(2) G Google Answer 10. [Spt] Consider the arrangement of two point charges, equal in magnitude, shown in the figure charges shown? Choose all the correct statements (AC,BE, etc.). Which of the following statements are correct if a certain charge is released from rest in the vicinity of the two A) A positive charge at point 'd' moves up. B) A positive charge at point b' moves up. C) A positive charge at point 'a moves to the lower-left D) A positive charge at point 'c' moves to the lower-left E) A negative charge at point'e' moves up Answ 11. [5p] Two charges, 0,-270 pC and Q,-5.7pC, are located at ports (o,-3.50 cm) and Submit All Answers +3.50 cm), as shown m the figure

Explanation / Answer

A, C

A) because a positive charge at D has greater force of attractration with -ve charge than force of repulsion with +ve charge , So it accelarates upwards,

Since Fnet = Ma ,& Fnet = Fattraction - F repulsion .

C) because it first moves downwards since repuslion with +ve and also attracion with -ve charged particle. Then after it moves slightly down, the distance from a to -ve is less , so attractive force overcomes repuslive force, and tends to move downward left.
