please write by hand thakk you 4. An electron (q=-1.6 x 10-19 C) experiences a force of 6.8 x 10-15 N as it moves with a velocityof 4.7 x 104 m/s across the two magnets as shown in the below figure.Pole 2a) Find the magnitude of the magnetic field.Velectronb) What is the correct direction of its magnetic force?c) Label the correct polarity of the magnets.Pole 1 5. The figure below is a simple pendulum with a 450-g mass attached to it. Its maximumdisplacement is found at point D and its maximum speed of 0.34 m/s is found at point C. If thependulum completes 13 cycles in 15.0 s, answer the following questions.Da) Calculate the frequency of this deviceb) Find its period of vibrationc) Find the length of the pendulumd) If the pendulum swings a total angle of 280, find its amplitudee) Calculate the kinetic energy at the lowest position of the pendulum
