Question

10. Two forces 20 N and 40 N are acting simultaneously at a point. If
the angle between the two forces is 45°, find the magnitude of
their resultant

11. If two forces of 30 N and 40 N act simultaneously on a particle
inclined at 60° to each other, find the magnitude of the resultant​

Answer 1

Step-by-step explanation:

In mathematics, a matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns. For example, the dimension of the matrix below is 2 × 3, because there are two rows and three columns: {\displaystyle {\begin{bmatrix}1&9&-13\\20&5&-6\end{bmatrix}}.}
