Two point charges lie on the x axis. A charge of 6.5 μC is at the origin, and a charge of -9.5 μC is at x=10.0cm. What is the net electric field at x=−4.0cm ? What is the net electric field at x=+4.0cm ?

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
