Design and explain a series of tests in order to characterise an electric motor used in a screwdriver. The tests should measure:

1- The no load speed of the motor (rad/s)

2- The stall torque of the motor (Nm)

3- Motor coil resistance (internal resistance in ohms)

Note: Please carefully explain how you would carry out a series of tests to determine the data listed above for an electric screwdrivers DC motor.

    Pls help with all questions a) A charged particle travels undeflected through perpendicular electric and magnetic fields whose magnitudes are 4000 N/C and 20mT, respectively. Find the speed of the particle if it is an alpha particle. (Alpha particle is a helium nucleus-a positive ion with a double positive charge of +2e.) I don't understand how the answer is v= 2.0*10^5 m/s. How could the velocity be independent of the charge since v = F / qBsinθ and q =2e?...
