the brass base plate of any outdoor sculpture; it experiences shear forces as result of earth quake. the frame is 0.80m square and 0.50cm thick. how large a force must be exacted on each of it edges if the displacement x is 0.16mmg(here force are applied tangent to opposite surface of the of the object. the deformation x is exaggerated for clarity)

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
