The electric field in a velocity selector is generated by two parallel plates separated by 5.00 cm with a potential difference of 90.0 V. If the magnetic field is 1.400e-1 T, at what speed will particles pass through undeflected

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

overcharge is the right answer system

answer; how far out of place which the object finished relative to the starting location;
