1.

A 10 kg body on a rough plane (μ = 0.25) inclined at 30° is pulled by P at 0° above the line of greatest slope and is about to move up. Which option is correct? (g = 9.8)

P = 70.22 N, R = 84.87 N

P = 70.22 N, R = 98 N

P = 27.78 N, R = 84.87 N

P = 70.22 N, R = 101.8 N

2.

A 5 kg body on a rough plane (μ = 0.3) inclined at 45° is pulled by P at 15° above the line of greatest slope and is about to move up. Which option is correct? (g = 9.8)

P = 45.04 N, R = 23.48 N

P = 41.69 N, R = 49 N

P = 43.16 N, R = 23.48 N

P = 41.69 N, R = 23.48 N

3.

A 5 kg body on a rough plane (μ = 0.3) inclined at 37° is pulled by P at 0° above the line of greatest slope and is about to move up. Which option is correct? (g = 9.8)

P = 41.23 N, R = 49 N

P = 41.23 N, R = 39.13 N

P = 41.23 N, R = 46.96 N

P = 17.75 N, R = 39.13 N

4.

A 5 kg body on a rough plane (μ = 0.25) inclined at 37° is pulled by P at 30° above the line of greatest slope and is about to move up. Which option is correct? (g = 9.8)

P = 39.63 N, R = 19.32 N

P = 39.63 N, R = 58.95 N

P = 26.59 N, R = 58.95 N

P = 39.27 N, R = 19.32 N
