A charge of 6.50 ✕ 10-9 C and a charge of -4.00 ✕ 10-9 C are separated by a distance of 0.6 meters.
Find the position at which a third charge, of 11.0 ✕ 10-9 C, can be placed so that the net electrostatic force on it is zero.
I thought you solved this the same way as you would if you were solving this problem with a unknown test charge but that wasn’t true. So how do you solve it lol2 AnswersPhysics1 year ago
PHYSICS HELP PLEASE! A satellite is orbiting a distant planet of mass 3.4e25 kg and radius 79100 km...?
A satellite is orbiting a distant planet of mass 3.4e25 kg and radius 79100 km. The satellite orbits at a height of 9180 km above the surface of the planet.
a) Determine the acceleration due to gravity at the location of the satellite orbit.
b) Determine the velocity of the satellite in this orbit.
c) What is the period of the satellite in this orbit?1 AnswerPhysics1 year ago
Do you think that protectionist policies (such as quotas and tariffs to reduce the flow of imports into the U.S) are good strategies for improving the U.S balance of trade?3 AnswersEconomics1 year ago
I’ve been stuck on the second part of this problem for forever.
Point charges of 7.00 µC and −2.50 µC are placed 0.100 m apart. (Assume the negative charge is located to the right of the positive charge. Include the sign of the value in your answers.)
I already got part A which asked “Where can a third charge be placed so that the net force on it is zero?”
I can’t figure out part B: What if both charges are positive?2 AnswersPhysics1 year ago
A man is standing beneath two rain clouds, equidistant from each cloud, as shown in the figure. Cloud A has an excess of 6.6*10^4 negative charges while cloud B has 6.6* 10^4 positive charges (where a charge has magnitude e).
Cloud A and B are 0.5 km apart and 2 km above the man (I don’t know how to insert the diagram, sorry!)
