The vernier constant of Vernier callipers is and it has zero error of . While measuring diameter of a sphere, the main scale reading is and coinciding vernier division is 5 . The corrected diameter will be .
View answer and explanation
Correct option: A
180
Option A (180) is correct because the corrected diameter is calculated by adding the main scale reading and vernier scale reading, then correcting for the zero error.

Statement-I: Random errors can be positive or negative.
Statement-II: Cause of random errors are uncertain. An object is moving through the liquid. The viscous damping force acting on it is proportional to the velocity. Then dimension of constant of proportionality is The error due to parallax is a: 2.34 is obtained by rounding of the number The dimensional formula of self-inductance is The dimension of is that of
