Plzzz solve all question it's urgent? 7. The system shown in this figure is in equilibrium. Calculate the tension in the string.(a) 30 N(b) 12 N(c) 25 N(d) 10 N5 kg-30°8. A block of mass m is pulled along a rough horizontal floor by an applied force Tasshown. The magnitude of the normal force ñ exerted on the block is given:(a) n = mg(b) n = mg-T sin 0T(c) n = mg + T cos 0K²(d) n = mg - T cos 09. A stone is tied to a string and whirled in a vertical circle at a radius (r).Which of the following is NOT true?(a) The tension is the maximum when the stone is at the bottom of the circle.(b) The tension force and the weight of the stone always affect the centripetalforce.(c) The tension is the least when the stone is at the top of the circle.(d) The tension force is the same everywhere in the circle.10. A roller-coaster car has a mass of 500 kg when fully loaded with passengers. If tvehicle has a speed of 20 m/s at point A, what is the force exerted by the track on tcar at this point if radius r = 10 m?(a) 5000 N(b) 25000 N(c) 6000 N(d) 1000 N2/7
