Q2. The force of attraction due to a hollow spherical shell of uniform density, on a point mass situated inside it, is
Answer : Option B
Explaination / Solution:
The gravitational force acting by a spherically symmetric shell upon a point mass inside it, is the vector sum of gravitational forces acted by each part of the shell, and this vector sum is equal to zero. That is, a mass m within a spherically symmetric shell of mass M will feel no net force
Q3. Difference between ionic (electrolytic) and electronic conductivity is that electronic conductance takes place in metals by ________ conductance takes place in solutions by ions
Answer : Option A
Explaination / Solution:
Electrolytic conductivity is due to the movement of ions and electronic conductivity is due to the movement of electrons.
Q4. in n-type semiconductor majority carriers and minority carriers are respectively
Answer : Option B
Explaination / Solution:
N-type semiconductors have a larger electron concentration than hole concentration. The term n-type comes from the negative charge of the electron.
In n-type semiconductors, electrons are the majority carriers and holes are the minority carriers.
N-type semiconductors are created by doping an intrinsic semiconductor with donor impurities (or doping a p-type semiconductor as done in the making of CMOS chips). A common dopant for n-type silicon is phosphorus.
