Q1: A 2.0 m long wire shown in the figure carries a current of 4.0 A and lies in a uniform magnetic field B given as B = (3 i + 4 j ) T. Find the magnetic force on the wire in unit vector notation. Q2: An electron is accelerated through a potential difference of 100V and then enters a region of uniform electric and magnetic fields. The electron is observed to move in a straight path inside the fields. The magnitude of the magnetic field B is 5.0 T and directed into the page as shown in the figure while the E direction is not known. a) What is the velocity of the electron as it exits the potential difference? b) What is the magnitude and direction of magnetic force applying on the electron? c) What is the magnitude and direction of the force due to the electric field? d) What is the magnitude and direction of the electric field E ? -V +V B E d
