(A) It is given that (q ) = +2.6 uC
d = 31 cm = 0.31 m
Force on charge 2 due to charge 1
On putting the values we get
On solving we get
F21 = 1.266 N
Now force on charge 2 due to charge 3
On putting the values we get
On solving , we get
F23 = 3.798 N
Now force on charge 2 due to charge 4
On putting the values we get
On solving , we get
F24 = 2.532 N
Now all forces are shown in the figure
In the x direction
FX = -F23 -F24Cos45 = -3.798 -
2.532Cos45 = - 5.588 N
In the Y direction
FY = F24Sin45 - F21 = 2.532Sin45 -
1.266 = 0.524 N
Therefore the magnitude of the force would be
F = 5.613 N
Now the direction would be
in clockwise direction from q3 - q2
direction
Now in counterclockwise direction it would be
= 180 +
= 174.64
o in counter clockwise direction from q3 -
q2 direction
