Question

Electric Field from Point Charges wo point charges (q1 4.8uc and qz 8.2 pC) are fixed along the x-axis, separated by istanced 7.6 cm. Point P is located at a d (x,y) (d,d). What is Ex(PO, the value of the x-component of the electric field produced by q1 and q2 at point P? You currently have 1 submissions for this question.

A third point charge q3. 2.1 uc is now positioned along the y-axis at a distance d 7.6 cm from q1 as shown. What is E Ph, the xcomponent of the field produced by all 3 charges at point P? N/C You currently have 0 submissions for this question. Only 10 submission are You can make 10 more submissions for this question. O Suppose all charges are now doubled (i.ee.,q1 -9.6 uc, q2 164pc, qu 4.2 VCO, how will the electric field at P change? Its magnitude will increase by less than a factor of two and its direction will remain the same

Explanation / Answer

3)

Ex = (- 9*10^9*4.8*10^-6 ) / (2*7.6*10^-2^2) *cos(45) + (9*10^9*2.1*10^-6)/(7.6*10^-2^2)

= 1.30*10^6 N/C

4)

Its magnitude will double and its direction will remain the same

5)

There is no change you can make to q1 that will result in the electric field at point P being equal to zero
