MCQ
A circular loop is kept in that vertical plane which contains the north-south direction. It carries a current that is towards south at the topmost point. Let $A$ be a point on axis of the circle to the east of it and $B$ a point on this axis to the west of it. The magnetic field due to the loop :-
  • A
    is towards east at $A$ and towards west at $B$
  • B
    is towards west at $A$ and towards east at $B$
  • ✓
    is towards east at both $A$ and $B$
  • D
    is towards west at both $A$ and $B$
✓

Answer

Correct option: C.
is towards east at both $A$ and $B$
c

A sample initially contains only $U -238$ isotope of uranium. With time, some of the $U -238$ radioactively decays into $Pb -206$ while the rest of it remains undisintegrated.

When the age of the sample is $P \times 10^8$ years, the ratio of mass of $Pb -206$ to that of $U -238$ in the sample is found to be $7$ . The value of $P$ is. . . . . .

[Given : Half-life of $U-238$ is $4.5 \times 10^9$ years; $\log _e 2=0.693$ ]
