A point charge q_1=-4.00\;{\rm nC} is at the pointx = 0.600 meters, y = 0.800 meters, and a second pointcharge q_2=+6.00\;{\rm nC} is at the pointx = 0.600 meters, y = 0.

A)Calculate the magnitude E of the net electric field at the origin due tothese two point charges.

B)What is the direction, relative to the negative x axis, of the net electric field at the origin due to these two pointcharges.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.

Acertain radio station broadcasts radio waves that have a wavelength of 298cm what is its broadcast frequency?

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
