An electric dipole is orientated antiparallel to an electric field e. find the work done by the electric field to reorientate it along the field. (0.5p) consider an ellipsoidal perfect conductor. two identical charges q are located at a distance l from its surface on the major (long) and minor (short) axes. which charge will experience stronger electrostatic force? (0.5p) a flat capacitor with two plates separated by air is charged to q. thereafter, the space between the plates is filled with water by keeping the potential difference unchanged is the energy which can be extracted from the capacitor larger, equal, or smaller than the energy required to charge the air-filled capacitor?

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
