The path of an electron, traveling at 3.7 × 10^4 meters/second, is making a right angle to a magnetic field. a single electron experiences a force of 2.2 × 10^-15 newtons while in the field. what is the strength of the magnetic field? the vaule of q = -1.6 × 10^-19

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.
