If you suddenly let go of the rope, the brick will move in a direction tangent to the circle at that point. The only cause of circular motion is centripetal force which is tension of string or indirectly force of hand in this case. As soon as you vanish it, no circular motion is possible and projectile motion is performed.
The 'pull' of the sun makes the Earth go around it. It can be compared with you holding a string with a piece of stone attatched to the end. If you start 'moving' the stone (as the Earth does) the movement will take the form of the stone speeding in a circle. That is caused by you exercising - through the string - a gravity-like 'pull' on the stone. If the sun suddenly would disappear, the same thing would happen as when you, spinning the stone around on your string, would suddenly 'disappear' and so let go of the string. The stone then would fly away in a straight line in the direction it was going when you released the string. In the same manner, the Earth would immediately stop speeding around in a circle and fly off in a straight line.
Think of swinging a ball around and around on the end of a string. The ball will stay straight out at the end of the string. The ball stays suspended at the end of the string because the moving ball wants to go straight but it can't because the string is holding it -- keeping it from flying away. The force the string is exerting on the ball is called centripetal force.Moons rotate around their planets just as the ball swings around on the string. The planet's gravity acts as the string, holding the moon from flying off into space.
To raise the pitch (frequency), put more tension on one end of the string. To lower the pitch, put less tension on one end of the string. For instance, on a guitar, tighten the string for a higher pitch. Loosen the string for a lower pitch. Additionally, if you have a guitar string already mounted and tensioned. You may place your finger in the middle of the string, and the pitch will go up one octave. Each time you halve a tensioned string, it produces a pitch one octave higher.
You've specified that the two forces act horizontally, but you've said nothing about how they're arranged relative to the string. -- Are the forces pulling in opposite directions on opposite ends of the string ? -- Are the forces both acting at the same end of the string, with the other end tied to a wall ? -- Are the forces in the same plane ? If so, is the string also in that plane ? I can give you configurations in which the forces are horizontal, and the tension in the string is anything you want between zero and 2,020 N. In fact, if both ends of the string are fastened to walls, and the horizontal forces push on the center of the string and perpendicular to it, then you can create any tension you want in the string, up to the breaking limit of the walls.

As force acting in a circular path is always tangential to the path
to indicate end of string
Wrap the string around the cylinder, mark where the end of the string touched itself, remove the string, and measure from the end of the string to the mark.
Character zero (the byte with the decimal value zero) is sometimes used to end a string. But in other cases, the size of the string is stored at the beginning of the string, and there is no end-of-string character. This allows any character to be included in the string.
The exact best method depends on a lot of unstated factors, such as the length and strength of the string, and whether there are any tools to hand. Also, do the children want to break the string roughly in the middle, so as to have two roughly equal pieces, or does it not matter where the string breaks? Each pulling one end is unlikely to be the best method. One or both children might fall over backwards when the string breaks, or the weaker child might be drawn towards the stronger one. A better option would be for one child to stand on the middle of the string and press downwards, while the other holds one end of the string in each hand and pulls upwards. If that doesn't work, both children could stand with one foot on the middle of the string and both could pull the ends upwards simultaneously.

A string has a node at the fixed parts of each string end.
