Question

До тіла прикладені сили 20 ні 18 н, напрямлені протилежно. Чому дорівнює рівнодійна цих сил? А:20 НВ:38 НС:18 НD:2 Hдопоможіть пожалуста​

Answer 1

Ответ:

R=F1-F2=20-18=2H

D:2H

Answer 2

Calculation of Resultant Force

To find the resultant force when two forces are applied in opposite directions, we can use the formula:

Resultant force = |F1 - F2|

Where F1 and F2 are the magnitudes of the two forces.

In this case, the forces are 20 N and 18 N, and they are directed in opposite directions.

Calculation

Using the formula, we can calculate the resultant force:

Resultant force = |20 N - 18 N| = |2 N| = 2 N

Therefore, the resultant force of these two forces is 2 N.
