Correct option is (4)
The Arrhenius equation is given as k = A e-Ea/RT
∴ ln k = ln A - Ea/RT
ln k v/s 1/T gives a straight line graph with slope = -Ea/R and intercept = ln A
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
