Three spiders are resting on the vertices of a triangular web. The sides of the triangular web have a length of a = 0.90 m, as depicted in the figure. Two of the spiders (S, and S3) have +6.8 µC charge, while the other (S2) has -6.8 µC charg al2 a/2 (a) What are the magnitude and direction of the net force on the third spider (S3)? magnitude direction ° counterclockwise from the +x-axis (b) Suppose the third spider (S3) moves to the origin. Would the net force on the third spider (S3) be greater than, less than, or equal to the magnitude found in part (a)?

If only one answer is correct, would it be A or C? Or could both be correct? Please explain.

An object is dropped from rest and takes 2.42 seconds to reach the ground below. From what distance above the ground was it dropped? State this as a positive number and assume it has proper SI Units.

Problem 4: The center of a moon of mass m= 2 x 1023 kg is a distance D = 28 × 10° km from the center of a planet of mass M = 19.9 × 1023 kg. At some distance x from the center of the planet, along a line connecting the centers of planet and moon, the net force on an object will be zero.

A squirrel is trying to locate some nuts he buried for the winter. He moves 5.10 m to the right of a stone and digs unsuccessfully. Then he moves 1.00 m to the left of his hole, changes his mind, and moves 8.10 m to the right of that position and digs a second hole. No luck. Then he moves 9.90 m to the left and digs again. He finds a nut at last. What is the squirrel’s total displacement from its starting point?

A map in a pirate’s log gives directions to the location of a buried treasure. The starting location is an old oak tree. According to the map, the treasure’s location is found by proceeding 7.45 paces North from the oak tree and then 6.62 paces Northeast. At this location, an iron pin is sunk into the ground. From the iron pin, walk 2.59 paces South and dig. How far (in paces) from the oak tree is the spot at which digging occurs?
