Questions and Verified Answers |
Already Graded A+
Two charged balls are repelling each other as they hang from the ceiling.
What can you say about their charges? - 🧠ANSWER ✔✔both are positive
or both are negative
When you rub a plastic rod with fur, the plastic rod becomes negatively
charged and the fur becomes positively charged. As a consequence of
rubbing the rod with the fur, - 🧠ANSWER ✔✔the rod gains mass and the fur
loses mass
, when 1.0 uC point charge is 18m from a second point charge, the force
each one experiences is of 1.0 uN. what is the magnitude of the second
charge? - 🧠ANSWER ✔✔36 nC
if we increase charge 1 to 5Q, what is the magnitude of F1 (3N)? (F1 and
F2 repel each other) - 🧠ANSWER ✔✔15N
Two balls with charges +Q and +4Q are
fixed at a separation distance of 7R. Is it
possible to place another charged ball Q0
on the line between the two charges such
that the net force on Q0 will be zero? - 🧠ANSWER ✔✔yes, independent of
the sign or value of Q0
an asteroid of mass 58,000kg carrying a charge of 15 uC is 180m from a
second asteroid of mass 52,000 kg carrying a charge of 11uC. What is the
magnitude of the net force the asteroids exert upon each other, assuming
we can treat them as point particles. - 🧠ANSWER ✔✔0.000040 N
two equally charged tiny spheres of mass 1.0 g are placed 2.0cm apart.
when released, they begin to accelerate away from each other at 414
