A long straight metal rod has a radius of 2.0 mm and a surface charge of density 0.40 nC/m2. Determine the magnitude of the electric field 3.0 mm from the axis.

Explanation:

Gauss Theorem

E2πrL=o2πRL/εo

then

E=oR/(rεo)

E=(0.4*10^-9*2*10^-3) / (3*10^-3*8.85*10^-12)

= 30.13 N/C

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
