Question

a string is stretched by two equal when the opposite
forces 10 n each the tension in the string us

Answer 1

Answer:

Explanation:

The use of word stretch gives the impression that the string is elastic and may get extended. I think the the string is pulled by two equal and opposite forces 10N . The string remaining stationary implies that the two 10 N forces are nothing but Newton's third law forces viz., Action and equally opposite reaction force. If you tie one end of the string to a wall and pull it with a force 10 N the wall will exert an equal and opposite force of 10 N, the situation you have stated. 10N <-------------------------> 10N

T = 10 N

The tension in the string is still only 10 N.

(Tricky question, a way to confuse a beginner into thinking that it will be 20 N :) )

Answer 2

Answer:

Explanation:

its an action and reaction so if you exert 10N on the string the reaction force will be the same. so the tension T in the string is 10N

hope this helps :)
