Answer:

Explanation:
From the conservation of mechanical energy




Solve to velocity v2




Answer: 2.80 N/C
Explanation: In order to calculate the electric firld inside the solid cylinder
non conductor we have to use the Gaussian law,
∫E.ds=Q inside/ε0
E*2πrL=ρ Volume of the Gaussian surface/ε0
E*2πrL= a*r^2 π* r^2* L/ε0
E=a*r^3/(2*ε0)
E=6.2 * (0.002)^3/ (2*8.85*10^-12)= 2.80 N/C
Your answer is correct. No problem and Have a nice day
Answer:
I believe the answer is C
Explanation:
because centripetal force is generally assosiated with rotation and how fast something spins
This one is also using pre-conventional moral reasoning.
