1. A 2.2nC charge is at the origin and a -3.2nC charge is at x = 1.4cm a) At wha

Question

1. A 2.2nC charge is at the origin and a -3.2nC charge is at x = 1.4cm

a) At what x-coordinate could you place a proton so that it would experience no net force?

b) Would the net force be zero for an electron placed at the same position?

2. Objects A and B are both positively charged. Both have a mass of 550g , but A has twice the charge of B. When A and B are placed 40cm apart, B experiences an electric force of 0.53N .

a) What is the charge on A?

b) If the objects are released, what is the initial acceleration of A?

Explanation / Answer

he proton must be placed far from -4 nC and near to 2 nC as shown below.


<p>.......x.............<2 nC.>.........1 cm.............<.-4Nc>


k.2.p/x^2 = k.4.p/(1+x)^2

x=1/(sqrt2-1)

yes if electron placed at taht point it would be also zero

2. F = k(q1)(q2) / r
