Question

The coordinates of four points are A(1,2,3), B(7,-4,6), C(-5,-4,0) and D(-5,8,6). Three forces having direction BA (read as point B to
A), CA and AD have magnitude of 100N each. Find Component of resultant force perpendicular to line OA (N)​

Answer 1

Answer:

The distance between the points A(1, 2) and B(4, 6) is calculated below. AC = 4 ... In this case, x1 = −4, x2 = 5, y1 = −3 and y2 = 7. ... If C(3, 6) is the midpoint of line interval AB and A has coordinates (−1, 1), find the ...
