Answer:
Post the figure also..
Given: A B and C are equally charged, force acting on B due to A is 2 x 10^-6.
To find: Force on B due to C, Net force on B due to both charges
Solution:
- Now we have given three particles of equal charges.
- Now Coulomb's law of electrostatic force is :
F = kq1q2 / r^2
- Now putting values in formula we get:
2 x 10^-6 = 9 x 10^9 x q^2/ (0.015)^2
- Now force on B due to C will be:
F = 9 x 10^9 x q^2/ (0.01)^2
- Now equation both equations, we get:
F / 2 x 10^-6 = (0.015)^2 / (0.01)^2
- So, F = 4.5 x 10^-6 N
- Now when all charges are in line, the net force on middle charge will be:
F = F(bc) - F(ba)
F = 4.5 x 10^-6 - 2 x 10^-6
F = 2.5 x 10^-6 N
- But when charges are placed perpendicular, then:
F = √ ( F(bc)^2 + F(ba)^2 )
F = √ ( 4.5² + 2²) x 10^-6
F = 4.92 x 10^-6 N
Answer:
So Force on B due to C is 4.5 x 10^-6 N and Net force on B due to both charges in line is 2.5 x 10^-6 N and when perpendicular is 4.92 x 10^-6 N.
