Find an expression for the electric field e⃗ at distance x from the end of the rod. give your answer in component form. express your answer in terms of the variables q, l, x, unit vectors i^, j^, and appropriate constants.

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

im sorry i dont know

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
