NEET · Physics · Electric Charges & Fields · Field of a Charged Shell

Exercise and reference answers

Matching pairs

1. A

   Inside the shell (r<R)

   B

   E = 0

2. A

   At the surface (r=R)

   B

   E = k·Q/R²

3. A

   Outside (r>R)

   B

   E = k·Q/r² (acts like point charge)

4. A

   Potential inside

   B

   V = k·Q/R (constant)

5. A

   Potential outside

   B

   V = k·Q/r

Instructions

Flip cards to match each location to E and V.
