Homework Statement Two opposite point charges of magnitude 1.90e-6 C are located near the origin. The positive charge is at (1.50, 1.50) mm and the negative charge is at (−1.50, −1.50) mm. What is the magnitude of the dipole moment vector for this pair of charges? Homework Equations p =...

Homework Statement A particle with charge +7.88 μC is placed at the fixed position x = 3.00 m in an electric field of uniform strength 300 N/C, directed in the positive x direction. Find the position on the x-axis where the electric field strength of the resulting configuration is zero...

GOT IT thanks for the help!

2.4 / .0345 = 69.5652

the problem states millicoulombs not micro - t = .014375

I forgot to find the force using F=qe then you can plug it into f=ma A = .000035 .000035t = 2.40 - 0 t = .000014 would the acceleration be negative also since the field of strength is opposite the particle

0 = 2.40 + 9.8 (t) t = 9.8 / 2.4 = 4.08333

Vf = Vi +at ??

Homework Statement A particle of mass 1.20 kg with a charge of +2.30 mC is shot into a region with an electric field of strength 18.0 N/C, having a direction opposite the particle's velocity. If the particle has an initial speed of 2.40 m/s, how long does it take to come to a complete (though...

Wouldnt you need to know the time for angular velocity?

angular = radians / s

After you divide the torque by the length and force do you take the sin of that answer - because when you do it is very small??

Homework Statement You want to exert a torque of at least 35.0 N·m on a wrench whose handle is 0.150 m long. If you can provide a force of 355 N to the end of the wrench, what is the minimum angle at which you can apply the force in order to achieve the desired torque? Homework Equations...

Homework Statement A boy carries a sack on one end of a very light stick that is balanced on his shoulder, at an angle of 22.0 degrees up from the horizontal. The mass of the sack is 7.00 kg, and it sits 1.20 m from his shoulder. If his hand is 0.350 m from his shoulder, on the other end of...

Homework Statement A hamster runs in its wheel for 4.5 hours every night. If the wheel has a 6.8 cm radius and its average angular velocity is 3.0 radians per second, how far does the hamster run in one night? Homework Equations angular velocity = ang displacement / time The...
