Two stationary positive point charges, charge 1 of magnitude 3nC and charge 2 of magnitude 1.55 nC are separated from rest at the point midway between the two charges and it moves along the line connecting the two charges

Could someone . i have tried to solve myself but my calculation is off

An isotope undergoes radioactive decay by emitting radiation that has a –1 charge. what other characteristic does the radiation have?

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
