Atomic number = 26
Atomic mass = 26 + 30 = 56
Net Charge = 26 - 23 = +3
Hope this helps!
*It's nucleas. There are protons, neutrons and electrons.
Answer:
The magnetic field that will allow the electron to go through the region without being deflected is 
.
Explanation:
Given that,
Velocity of the electron, 
Electric field, 
We need to find the magnetic field that will allow the electron to go through the region without being deflected. It can be calculated as :
Here, 
So, the magnetic field that will allow the electron to go through the region without being deflected is .
Work is done when a force acts on an object AND the object moves in the direction of the force.
-- <em>Pulling a trailer up a hill. YES. </em> The trailer is moving in the direction of the pulling force.
-- Carrying a box down a corridor. No. The box is not moving in the direction of gravity (down) OR in the direction of your arm (down the corridor).
-- Suspending a heavy weight with a strong chain, No. There's a force (gravity) acting on the weight, but the weight is not moving at all.
-- Pushing against a locked door. No. There's a force (your muscles) acting on the door, but he door is not moving at all.
