Question

A small conducting spherical shell with inner radius a and outer radius bis concentric with a larger conducting spherical shell with inner radius c and outer radius d. The inner shell has a total charge of -19 and the outer shell has a total charge of +49. Select True or False for the following statements. ✓ The electric field in the region r <a is zero. The total charge on the inner surface of the large shell is +19. The electric field in the region card is zero. The total charge on the outer surface of the larae shell is +39. ✓ The total charge on the inner surface of the small shell is zero. The radial component of the electric field in the region r>d is given by +39/(4nɛor). The total charge on the outer surface of the small shell is -19. Use Gauss's Law.

Answer 1

The answer to your question is as follows, also see the last one i just typed itAlso, last one is True... As there's no charge on inner surface of inner shell and total charge on shell is -q, so whole charge is present on it's outer surface ie. -q...

39/ & Aface surface • Tinue a) electric field is o for sea, as no charge inside erca so Seeds so. True & eg' gets induced due to q' of the outer dad of small shell. surface False 2) As - there in outerseret of smalles Ord stone & eq on inner che of larger or de one, so there's an ê field. Also (². ds s – a tor cered. Total charge on outer suf ace is +39) Pome. as total charge on shell is conserved & eq on inner" meat of large shell, 80 +39 on outer net Do Tome 2) In a conductor, alt charge inside is always o. So, as no extra charge inside rea, so inner einface of small shell is zero. True. 2) As we know, je de s-q+49 +3 | E.4770? Ba Es 3q Co tre aussis law, 4TTE, 82 0 surface surface. to
