Academics

Q1. In accordance to one estimate, the first atomic bomb released an energy equivalent to 20 kilotons of TNT. If 1 ton of TNT releases about 4.0 109 J, how much uranium was lost through fission in this bomb? (Assume 208 MeV released per fission.)

Q2. An object with a net charge of 44 µC is placed in a uniform electric ?eld of 554 N/C, directed vertically. The acceleration of gravity is 9.81 m/s^2. What is the mass of this object if it ?oats in this electric ?eld?
