A charged particle (mass 2.9.0 micrograms) was travelling in a vacuum at 0.5.9 km/s at 30 degrees North of East at t = 0 when it entered a uniform electric field which exerted a constant force of 47 mN East on the particle for 8.8 ms. At t = 8.8 ms, the particle was 5.1238 m East and 2.596 m North of where it was at t = 0. During the 8.8 ms interval, the impulse exerted on the particle was N s East and the work done was J. At t = 8.8 ms, the momentum of the particle was kg m/s at degrees North of East, and the kinetic energy was Question 4 of 4 2 Points Click to see additional instructions In the PET (Positron Emission Tomography) scanner at iThemba LABS near Cape Town (which your course tutor Moment uses for his research), a positron emitter is used. A positron is the antimatter equivalent of an electron, with the same mass as an electron. When a positron and an electron meet, they annihilate each other, producing energy. This energy takes the form of two gamma photons (each with energy E = hf), emitted in opposite directions.The frequency of the photons emitted is x 1020 Hz, if the kinetic energies of the positron and electron were negligible
