What distinguishes mass from weight?
a. mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.
b. weight is a measure ofthe amount of matter in an object, while mass is a measure of the force of gravity on the object.
c. mass is a measure of an object's inertial force, and weight is the force exerted by that object on other objects.
d. mass and weight are synonyms and ultimately describe the same principle?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
