Q:

A parallel-plate capacitor of capacitance C1is  made  using  two  gold  plates.  Another parallel-plate capacitor of capacitance C2is made  using  two  aluminium  plates  with same  plate  separation,  and  all  the  four plates  are  of  same  area.  If gand aPare respectively  the  electrical  resistivities  of gold and aluminium, then which one of the following relations is correct?

A) C1>C2 B) C2>C1
C) C1pa = C2pg D) C1 = C2
 
Answer & Explanation Answer: D) C1 = C2

Explanation:

C1= capacitance of gold plates

C2=   capacitance   of   aluminium plates

rg= Gold’s resistivity

ra= Aluminium’s resistivity

As the capacitance depends on the shape,  size  &  geometrical  placing of  the  conductors  &  the  medium between them, hence, the value of capacitance  will  be  independent  of resistivity. Therefore, C1= C2

Q:

What occurs when an atom loses an electron?

A) The atom's radius decreases and the atom becomes a positive ion. B) The atom's radius increases and the atom becomes a negative ion.
C) The atom's radius decreases and the atom becomes a negative ion. D) The atom's radius increases and the atom becomes a positive ion.
 
Answer & Explanation Answer: A) The atom's radius decreases and the atom becomes a positive ion.

Explanation:

When an atom loses an electron it becomes a positive ion by acquiring negatively charged. When it loses electron, the atom's radius also decreased.

Q:

Which politician in British India had opposed to a Pakistan that would mean "Muslim Raj here and Hindu Raj elsewhere"?

A) Khan Abdul Ghaffar Khan B) Sikandar Hayat Khan
C) Maulana Abul Kalam Azad D) Rafi Ahmed Kidwai
 
Answer & Explanation Answer: B) Sikandar Hayat Khan

Explanation:

“Pakistan would mean a massacre,” the Premier of Punjab Sir Sikandar Hyat Khan predicted to the distinguished civilian Penderel Moon as early as in October 1938 ( Divide and Quit, page 20). That was well before the Muslim League adopted the Pakistan resolution on March 23, 1940, in Lahore, radically altering Sir Sikandar's draft just 24 hours before it was passed. He repudiated it because it dropped the organic linkbetween the two parts of India, which he had provided. He told the Punjab Legislative Assembly, on March 11, 1941, “We do not ask for freedom that there may be Muslim Raj here and Hindu Raj elsewhere. If that is what Pakistan means I will have nothing to do with it.”
