a.) What is the force of the 1.0 nC in the figure (in Newtons)
b.) Give the direction (degrees above horizontal)
There are two kinds of force that can be applied. It is called contact force as well as non-contact force. Contact force is the force that results through physical contact between objects. Non-contact force is force applied without physical contact.
F1 = 1.8*10^-4 cos60 + 1.8*10^-4 sin60
F3 = 1.8*10^-4 cos60 – 1.8*10^-4 sin60
Fnet = F1+F3 = 1.8% -4 N
The force’s direction is to the right
