Acharge of +q is fixed in space. a second charge of +q was first placed at a distance r1 away from +q. then it was moved along a straight line to a new position at a distance r away from its starting position. the final location of +q is at a distance r2 from +q.
what is the change in the potential energy of charge +q during this process?
kqq/r
kqqr/r12
kqqr/r22
kqq((1//r1))
kqq((1//

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
