1.	block of mass 8 kg acted by a force of 56 newton exerted by string in vertically upward position, system starts from rest, work done by tension in 10sec
Answer» Given:- MASS, m=8 kg Tension in the wire, T=56 N To Find:- WORK done by tension Explanation:- EXPRESSION of work done by force F is given by:- $W=F\times scos\theta \text{ where,}\\\\s=\text{distance travelled by the object}\\\theta=\text{angle between force and distance direction}\\\\\text{ATQ, tension is in vertical direction and distance is in horizontal direction }\Rightarrow\theta=90^{0}\\\\\Rightarrow W=F\times scos90^{0}=0J$

Answer»

Given:-

MASS, m=8 kg

Tension in the wire, T=56 N

To Find:-

WORK done by tension

Explanation:-

EXPRESSION of work done by force F is given by:-

$W=F\times scos\theta \text{ where,}\\\\s=\text{distance travelled by the object}\\\theta=\text{angle between force and distance direction}\\\\\text{ATQ, tension is in vertical direction and distance is in horizontal direction }\Rightarrow\theta=90^{0}\\\\\Rightarrow W=F\times scos90^{0}=0J$
