1) A particle carrying charge qA = -8 × 10^-4 C is placed at point A and a particle carrying charge qB = -2 × 10^-4 C is placed at point B.
a) Find the magnitude and direction of the electric field at point C.
b) Find the electric potential at point C.
c) Find the direction and magnitude of the electrostatic force acting on the particle carrying charge qC = -3 × 10^-5 C placed at point C.
d) How much work would one need to do to move particle qC from its location at C to infinity?
e) Is there a point along the line joining charges qA and qB where if you placed charge qC it will experience no acceleration? If so, where? Specify the distance to qA.
A 3-Phase stepping motor is to be used to drive a linear axis for a robot. The motor output shaft will be connected to a screw thread with a screw pitch of 5 mm. We want to be able to have a spatial control of at least 0.1 mm.
using booth's algorithm,write a program to include a procedure with mutiplies two 16 -bit signed numbers and produces a 32 bit result.the signed numbers are assumed to use a 2's complement notation,and both numbers are to be passed to your procedu..
build a cicuit that must be able to operate a 3 amp load of the LED while being able to operate at voltages around 3V or 6V. It must be able to keep the LED on constantly while also being able to pulse the LED.
If the surface heat flux varies linearly with x, such that q"s (W/m2) = 500x (m), what are the values of q, Tm,o, Ts,i, and Ts.o? Sketch the axial variation of T, and Tm. On the same figure, also sketch (qualitatively) the axial variation of Ts an..
