1. The amount of force required to keep a 6-kg object moving with a constant velocity of 2 m/s is N.
a. 0.333
b.2
c. 3
d. 6
e. 12
f. ... nonsense! A force is NOT required to keep an object in motion.

What is the electric force acting between two charges of -0.0045 c and -0.0025 c that are 0.0060 m apart? use fe=kq1q2/r^2 and k = 9.00 x 10^9 n*m^2/c^2 a. 1.7 x 10^7 n b. -1.7 x 10^7 n c. -2.8 x 10^9 n d. 2.8 x 10^9 n
