Question
Capter 20 Activities and Tutorials Forces in a Three-Charge System Constants Part A Couiombrs law for the magnitude of the force F between two particles with charges Q and Q' separated by a distance ds What ts the net force exerted ty these two charges on a therd charge 9s-52.5 C placed between q and o at Your answer may be positive or negative. depending on the dinection of the torce Express your answer numenicalty in newtons to three significant ngures View Available Hs 1 055m where K and permitivity of tree space Consider two pont charges located on the x axis one charge, G--100 DCis located at a-1.705 tm the second charge . 32 5 nC , ts atthe orign (z-00000) Provide FeedbackExplanation / Answer
We know that charges with same sign repel each and also other and charges with opposite sign attract each other
So
force on q3 due to q1 is attractive in nature.
direction:along -ve x-axis
magnitude=9*10^9*10*10^(-9)*52.5*10^(-9)/(1.705-1.055)^2=1.12*10^(-5) N
force on q3 due to q2 is repulsive in nature.
direction:along -ve x-axis
magnitude=9*10^9*32.5*10^(-9)*52.5*10^(-9)/(0-(-1.055))^2=1.38*10^(-5) N
net force is along -ve x-axis
net magnitude=2.5*10^(-5) N
