A) 0.035 J
B) 1.5 J
C) 3.75 J
D) 0.0375 J
Correct Answer: D
Solution :
Energy loss when the spheres are connected by wire is given by \[\Delta U=\frac{{{C}_{1}}{{C}_{2}}}{2({{C}_{1}}+{{C}_{2}})}{{({{V}_{1}}-{{V}_{2}})}^{2}}\] \[=\frac{(3\times {{10}^{-6}})\times (5\times {{10}^{-6}})}{2(3+5){{10}^{-6}}}{{(300-500)}^{2}}\] \[=\frac{15}{16}\times 4\times {{10}^{-2}}\]\[=0-0375\]joule
