Two charges are fixed along a horizontal axis. One is located atthe origin and has a charge of 1.0µC and the other is at x = 0.25mwith a charge of -2.0µC. (a) Where would a third particle be placedso that the net electric force on it due to thepresence of the other two is zero? (b) If the third particle mustbe placed between the two fixed ones, where would it be placed sothat the net electric force on it would be minimized? (c) Ignoringthe third particle, where on the x-axis will the ELECTRIC FIELD bezero?

A 5.0 µC point charge and a6.0 µC point charge are adistanceL apart. Where should a third point charge beplaced sothat the electric force on that third charge is zero? Iknowthat the third point must be between the other two charges butI donot understand how to calculate how many times L away fromthe5.0 µC point charge the third pointis. please show how tocalculate how many times L away fromthe 5.0 µC point charge thethirdpoint charge should be placed for the electric force onthatthird charge top be zero. thank you

two point charges, q1=-2 microC and q2= -2microC are located onthe y axis. The charge at q1 is located at y=+1m and charge q2 aty=-1m.

1. Determine the electric field at point P on the x-axis atx=0.5m. specify direction

2. calculated the electric force on a point charge particle withq3=3 microC placed at P. specify direction

3. if you place q3 in item (b) at the origin of the coordinatesystem O and release it, the charge remains at that position, forthe net force on it is zero. You now displace q3 by a smalldistance along the x-axis and release it again. does charge q3: (i)remain at the new position (ii) move further away from origin (iii)return to origin. justify your answer

4. a student replaces charge q'2 by a unknown charge q2. placingnow charge q3=3microC at y=0.5 on the y axis, he notes that q3remains at rest. find the value of q'2

1) A charge 5.01 nC is placed at the origin of an XY-coordinate system and a charge -2.03 nC is placed on the positive x-axis at x= 4.01 cm. A third particle, of charge 5.98 nC is now placed at the point x = 4.01 cm , Y = 3.02 cm.

 

a) Find the x-component of the total force exerted on the third charge by the other two.

 

B) Find the y-component of the total force exerted on the third charge by the other two.
