The Vernier scale of one of the calipers ( C 1 ) has 10 equal divisions that correspond to 9 main scale divisions. The Vernier scale of the other caliper ( C 2 ) has 10 equal divisions that corresponds to 11 main scale divisions. The readings of the two calipers are shown in the figure. The measured values (in cm) by calipers C 1 and C 2 , respectively, are:

A student performs an experiment to determine the Young's modulus of a wire by Searle's method. In a particular reading exactly 2 m long length and charge (i) magnetic flux (ii) rigidity modulus The current voltage relation of diode is given by I =(e1000v/T -1) mA The density of a solid ball is to be determined in an experiment . The diameter of the ball is measured with a screw gauge time where the applied voltage V is in volt and the temperature T is in kelvin. If a student makes an error measurin ± 0.01 V while measuring the current of 5 mA at 300K Write the dimensions of the following in terms of mass
