Unformatted text preview: before the block comes to rest? (b) How long is the block in contact with the spring before it comes to rest? 3) A sting is displaced from its equilibrium position and oscillates as shown below. If the frequency is 440Hz and the string has a length of 2 meters and a mass of 0.4kg, find the tension in the string? 4) Two charges, each equal to 2.90 uC, are placed at two corners of a square 0.500m on a side, as shown in the following sketch. Find the magnitude and direction of the net electric field at the third corner of the square, the point labeled 3 in the sketch....
