Question

how will you reduce the errors due to random effects? what would be the dimensions of a physical quantities force and density.​

Answer 1

Methods to reduce random errors

1. By taking repeated measurements to get an average value.

2. By plotting a graph to create a pattern and attaining the line or curve of best fit. In this way, the inconsistencies or errors are reduced.

3. By maintaining good experimental practice (e.g. reading from a correct position)

Dimension of density:

                            [Density] = [ML^-3] or [ML-3T^0]

Dimension of force:

                         Force= M^1 L^1 T^-2

Hope it helped.........
