The ends of a rope are held by two men who pulls on it with equal and opposite forces of magnitude $F$ each. Then the tension in the rope is
$F$
$2F$
$\frac{F}{2}$
Zero
A mass of $100\,kg$ is moved with uniform velocity under the influence of force $F$, then the force acting on the beam due to string connected to the ceiling ............ $N$
A rope of mass $5 \,kg$ is hanging between two supports as shown alongside. The tension at the lowest point of the rope is close to ........... $N$ (take, $g=10 \,m / s ^{2}$ )
In the figure, the tension in the horizontal cord is $30\,N$. Find the weight of the body $B.$ ............ $N$
A uniform beam of weight $W$ is attached to a vertical wall by a hinge $H$ . The beam is held horizontal by a rope as shown below. Which one of the following best shows the direction of the reaction force $R$ at the hinge ?
Which force act on body first action or reaction ?
