General Physics: (Chapter 23 )Electric field
A 7.50-nC point charge is located 1.80 m from a 4.20-nC point charge.
(a) Find the magnitude of the electric force that one particle exerts on the other.
(b) Is the force attractive or repulsive?
===================================================
Three point charges lie along a straight line as shown in Figure below ,
where q1 = 6.00 μC, q2 = 1.50 μC, and q3= 2.00 μC.
The separation distances are d1= 3.00 cm and d2= 2.00 cm.
Calculate the magnitude and direction of the net electric force on (a) q1, (b) q2, and (c) q3.
================================================
In figure below, determine the point (other than infinity)at which electric field equal zero
=====================================================================
Three point charges are arranged as shown in Figure below Find
(b) the direction of the electric force on the particle at the origin.

Exercise 7:
(a) Find the acceleration of the proton.
(b) Over what time interval does the proton reach this speed?
(c) How far does it move in this time interval?
(d) What is its kinetic energy at the end of this interval?
