Question

Three spiders are resting on the vertices of a triangular web. The sides of the triangular web have a length of a 0.46 m, as depicted in the figure. Two of the spiders (S1 and S3) have 7.7 uC charge, while the other (S2) has 7.7 C charge What are the magnituc and direction of the net forcc on th third spider (83)? magnitude 270 Counterclockwise from the +x-axis direction he third spider (5a) be greater than, less than. r equal to the magnitude found in part (a)? Suppose the third spider (53) moves t the origin. Would the force on areater than in part (a) less than in part (a equal to the part (a) maghitude and dirnetin 5.04357 the third spider (Sa) when it is resting at the oriqin? What are f the net farce magnitude the magnitude of the electric force? How do you find the total net force? N vou direction counterclockwise from the +x-axis 27C
