266297 Two wires are made of the same material and have the same volume. However wire 1 has crosssectional area \(A\) and wire 2 has cross-sectional area \(3 A\). If the length of wire 1 increases by \(\Delta x\) on applying force \(F\), how much force is needed to stretch wire 2 by the same amount:

266298 A rocket with a lift off mass \(20,000 \mathrm{~kg}\) is blasted upwards with an initial acceleration of \(5.0 \mathrm{~m} \mathrm{~s}^2\) Calculate the initial thrust (force) of the blast.

266299 An LCR series ac circuit is at resonance with 10 V each across \(L, C\) and \(R\). If the resistance is halved, the respective voltages across \(L, C\) and \(R\) are:

266300 A tall cylinder is filled with viscous oil. A round pebble is dropped from the top with zero initial welocity. From the plot shown in figure, indicate that represents the velocity ( v ) of the pebble as a function of time (t).
