A particle has a charge of 600oc and a mass of 0.6 nkg., Ask an Expert

Academics

Q. A particle has a charge of 600^oC and a mass of 0.6 nkg. This particle is placed in a uniform electric field of 1,200 N/C. Find the a) electrostatic force acting on the mass. If the particle is released from rest what is its acceleration.

Q. A 0.30-kg mass attached to the end of a string swings in a vertical circle (R = 1.6 m). At an instant when q = 50°, the tension in the string is 7.0 N. What is the magnitude of the resultant force on the mass at this instant?
