Question

I need help with number 1 please and round all numbers to three significant digits please 

01. Two conducting spheres are separated by 65.3 km.
One has a charge of +0.0776 C and the other has a
charge of -5.92 C. Calculate the electrostatic force
between them.
02. How much charge passes a single point in a wire in
0.15 seconds if a current of 1.44 A is flowing through
the wire?
03a. A 46 Q resistor, a 71 Q resistor, and a 91 Q resistor,
are connected in series and are attached to 120 V
potential difference.
a. What is the equivalent resistance of the three
resistors?
