Please answer the question in a step by step process with the correct answer

An object with mass m : 5.49 x 104kg and charge q : 3.7 x 1020 moves in a region where there is a constant magnetic eld E? : 0.54T; + 2.58T1'}. The only force on this object is the Lorentz force. At time t : Us the object is at F : 5.1mm\" and its velocity is 17 : 323%1'. (The input below will only mark answers correct if they vary by no more than 1% from the correct value.) What is the time rate of change of the angular momentum? if. 2 C 2 A. 2 A E = kg%1+ kg%3+ kgtk
