A uniform electric field is established by connecting the plates of a parallel plate capacitor to a 12v battery. A charge particle of +6.24x10 to the power -6c moves from rest from the positive plate to the negative plate. when the charge reaches the negative plate,it acquires a speed of 3.4m/s.what is{a} the mass of the charge particle and{b} its final kinectic energy?
The velocity of a particle is defined by Vx=100-t^(3/2) and Vy=100+10t-2t^(2) Where V is in m/sec and t is in seconds. The radius of curvature at the top of its path is?
