Consider a thin spherical shell of radius RR with centre at the origin, carrying uniform positive surface charge density. The variation of the magnitude of the electric field ∣E⃗(r)∣|\vec{E}(r)| and the electric potential V(r)V(r) with the distance rr from the centre, is best represented by which graph?Consider a thin spherical shell of radius R with centre at the origin, carrying uniform positive surface chargeConsider a thin spherical shell of radius R with centre at the origin, carrying uniform positive surface chargeConsider a thin spherical shell of radius R with centre at the origin, carrying uniform positive surface chargeConsider a thin spherical shell of radius R with centre at the origin, carrying uniform positive surface charge

Options

  2. BWhich enzyme is responsible for breaking down glycogen into glucose when the body needs it?
  3. CWhich enzyme is responsible for breaking down glycogen into glucose when the body needs it?
  4. DWhich enzyme is responsible for breaking down glycogen into glucose when the body needs it?

Correct answer

D. Which enzyme is responsible for breaking down glycogen into glucose when the body needs it?

Step-by-step solution

For a thin uniformly positive charged spherical shell (i) Inside the shell at any point E=OE=O and V=14π∈0qR=V=\frac{1}{4 \pi \in_{0}} \quad \frac{q}{R}= constt. where q=q= charge on sphere R=R= Radius of sphere (ii) Outside the shell at any point at any distance rr from the centre E∝1r2E \propto \frac{1}{r^{2}} and V∝1rV \propto \frac{1}{r}
