You need to calculate the maxheight attained from ground....you might have calculated it from top of the tower perhaps.....anyway don't worry it happens....exam pressure.....

Apply Cauchy Schwarz inequality on LHS,you will observe that LHS is greater than equal to the RHS.Then apply the equality condition Cauchy Schwarz inequality( in Cauchy Schwarz inequality,the equality exists when the ratio of terms is constant).You will get that 1=a=b.Therefore (1,1) is the only solution.

Kindly confirm the answer for the conditions for current to flow in the wire connected to circuits.

I marked “current will flow if E1/R1 not equal to E2/R2.”

I know that if the wire connects 2 points, then those 2 points potential is same. But I got confused during exam and trusted "Kirchoff's law" for junctions.

To make things simple think this way....the circuits are initially separate..consider any one of the circuit.... current is e/r....now connect them write Kirchoff's voltage law for the same circuit......did you find that the current again remains the same......so what can be concluded is that current did not flow through the wire.....

actually 2014 paper was quite tough (cutoff was only 42). so scoring 78 in that is indeed an achievement

i got rank 59 last year coz the paper was slightly easier last year than 2014 . One of my friend got 82 last year still ended up on rank 14

\((1+a+b)^2=3(1+a^2+b^2)\)

\(\iff 2a^2+2b^2-2a-2b-2ab+2=0\)

\(\iff (a-1)^2+(b-1)^2+(a-b)^2=0\)

Hence, \(a=b=1\) only. – Akshay Yadav · 5 months, 1 week ago
