$^{235}_{92}U + ^{1}_{0}n \rightarrow ^{89}_{36}Kr+3 ^{1}_{0}n+X_{X}^{A}$
$92+0=36+Z$
$\Rightarrow Z=56$
$235+1=89+3+A$
$\Rightarrow A=144$
So, $^{144}_{56}Ba$ is generated
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
