A +5.7 C and a -3.5 C charge are placed 25 cm apart. Where can a third charge be placed so that it experiences no net force? (Restrict your analysis to a linear one.)
physics
Four 7.5 kg spheres are located at the corners of a square of side 0.60 m. Calculate the magnitude and direction of the gravitational force on one sphere due to the other three.
physics
If a negative charge is initially at rest in an electric field, will it move towards a region of higher potential or lower potential? What about a positive charge? How does the potential energy of the charge change in each case?

Why do you lose weight when you enter a tunnel passing through a mountain tunnel or walk inside a skyscraper?
physics
we are hurt because wen the weight falls on our hand it applies force on our hand but when the hand tries to pass the force over to the table it does not pass . this is because the force of the table on the hand is higher than the force of the hand on the table.......is this c...

It is fairly easy to catch a 20 N steel weight dropped from a height of 0.25 m or so. But if you attempt to catch the weight while resting your hand flat on a table, you are likely to be injured. Explain.

Point X and Y are 30.0 mm and 58.0 mm away from a charge of +8.0 C. a. How much work must be done in moving a +2.0 C charge from point Y to point X? b. What is the potential difference between points X and Y? c. Which point is at the higher potential?

m nt good at physics .....i don't understand physics so well .....i try to do the problems but they don't make sense at all .....so i ask it here ...and wen someone helps me ...i understand them and then only write them ......m not cheating .....i just need help to und...
