Problem 17.39 Two point charges are separated by 25.0 cm (see (Figure 1). Assume that ah --6.50 nc and q2 12.5 nC Figure 1 of 1 10.0 cm 25.0 cm Submit My Answers Give Up Correct Part C What would be the magnitude of the electric force this combination of charges would produce on a proton at A Express your answer in newtons to three significant figures. Submit My Answers Give Up Incorrect; Try Again; 2 attempts remaining Part D What would be the direction of the electric force this combination of charges would produce on a proton at A? The force would be directed to the lefL The force would be directed to the right Bubm My Answers Give Up Correct Provide FeedbackExplanation / Answer
c) Force due to q1 = kq1q / a^2
= 9*10^9*6.5*10^-9*1.6*10^-19 / 0.15^2
= 4.16*10^-16 N to the left
force due to q2 = 9*10^9*12.5*10^-9*1.6*10^-19 / 0.1^2
= 1.8*10^-15 (to the right)
net force = 1.8*10^-15 - 4.16*10^-16
= 1.384*10^-15 N ( to the right)
