a wire of length 10cm carrying a current lies at right angle to a magnetic field of flux density 5 milli tesla. if 10,^18 electrons pass a point in the wire each second, determine the current flowing in the wire and the force acting on it (q electron= 1.6×10^-19)

beta is electron from nucleus

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

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

its a circle not a square that's simple silly.
