Please q16 How is D is correct when the sum of forces anti clockwise & clockwise are not equal. Oh i dont understand please anyone explain me.

i didnt really understand .. why not B for example? B has only one loopI had already uploaded this paper . _ .

Here where ever you see the junctions, the current divides, Try all the options and check on which two of the ammeter has same currents passing.
So in D option, only one loop is formed so every where in the circuit the current would be same. Hence D.
If der r 2 or more wires protruding from a single point, then da current is split. When current is split, da value of current is not da same everywhere in da circuit. Da only circuit arrangement, where dis is not da case is arrangement D. In D, a single wire is connecting every meter, so current is same throughout circuit
m(60) + m(-40) = 2mV
Answer is B ?
m(60) + m(-40) = 2mV
60m - 40m = 2mV
2mV = 20m
[ V = +10 cm/s ]
Answer: A
shoot!! sign ka bheelo jata hoon hamesha :''( *thats the main key point in all mcqs* *sign changes as direction changes* kitkat <3 :P thanx hadim(60) + m(-40) = 2mV
60m - 40m = 2mV
2mV = 20m
[ V = +10 cm/s ]
Answer: A
thora sa concentrate:O i didnt add them i took mv on the right side

For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
