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

An object with mass m = 5.49 x 10 *kg and charge q = 3.7 x 10 2C moves in a region where there is a constant magnetic field B = 0.54Ti + 2.58Tk. The only force on this object is the Lorentz force. At time t = 0s the object is at r = 5.1mi and its velocity is v = 323m j. (The input below will only mark answers correct if they vary by no more than 1% from the correct value.) What is the Lorentz force on this object? F = Nit Nit Nk
