The tension on the string = <u>12 N </u>and acceleration of the mass = <u>2.4 m/s² </u>of the two masses .
<h3>Tension of a string :</h3>
The tension of a given strand of string or rope is a result of the forces pulling on the rope from other end. As a reminder, force = mass × acceleration. Considering , the rope is stretched tightly, any change in acceleration or mass in objects the rope is supporting will cause a change in tension within the rope.
<h3>Evaluating the numerical :</h3>
m₁ = 3kg
m₂ = 5kg
F = 20 N Applied on 3 kg
F - T = m₁a
T = m₂a ( T = tension )
F - m₂a = m₁a ( a = acceleration )
F = ( m₁ + m₂ )a
20 N = ( 3 kg + 5 kg )a
a = 2.4 m/s²
When F is applied on 3 kg block
T = m₂a
T = 5 × 2.4
T = 12 N
<h3>What is acceleration explain?</h3>
Acceleration, is defined as rate at which velocity changes with time, in terms of both speed and direction. some extent or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated whether or not the speed is constant, because the direction is continually changing
