Question description
The current voltage relation of diode is given by (I=e^1000V/T-1 )mA, where the appliedV is in volts and the temperature T is in degree kelvin. If a student makes an errormeasuring Β± 0.01 V while measuring the current of 5 mA at 300 K, what will be theerror in the value of current in mA?From a tower of height H, a particle is thrown vertically upwards with a speed u. Thetime taken by the particle, to hit the ground, is n times that taken by it to reach thehighest point of its path. The relation between H, u and n is:A mass βmβ is supported by a massless string wound around a uniform hollow cylinderof mass m and radius R. If the string does not slip on the cylinder, with whatacceleration will the mass fall on release?
