Levi Malone is sledding with his friends in the frozen tundra. Angered by a coarse comment, he decides to separate from the group rather than
escalate the situation. He momentarily exerts a 30 N force on the rope
which is attached to his 4.8 kg sled. The rope makes an angle of 21° with
the horizontal nearly frictionless surface. determine the acceleration

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
