please answer all parts
В.
In the situation pictured at right, a point
charge q =+1.5 nC is attached to one end of a 4.0
m long massless string. The other end is attached to
the top of a 3.0 m step. A point charge Q2 of
magnitude 3.7 nC is located at the bottom of the
step. In this situation, the string is perfectly
horizontal.
1= 4.0 m
mi = ?
qi =+1.5 nC
i.
Is the charge Q2 positive or negative?
Explain your reasoning.
|Q2| = 3.7 nC
ii.
Determine the magnitude of the electric force on qi caused by Q2. Show your work.
ii.
Determine the magnitude of the tension force in the string. Show your work.
iv.
Determine the mass m¡ of the charge q1. Show your work.
h = 3.0 m
