While measuring length with a scale, the scale should be placed –
  • Slanted to the object
  • Exactly along the length of the object
  • Above the object
  • Diagonally on the object
If the zero mark of a scale is broken, measurement can be taken by –
  • Using any other scale only
  • Starting from another known mark and subtracting the reading
  • Estimating the value
  • Ignoring the first few centimetres
The eye should be placed –
  • At an angle to the scale
  • Vertically above the point of measurement
  • From the side of the scale
  • At any convenient position
The error due to incorrect eye positioning while measuring length is called –
  • Measurement error
  • Parallax error
  • Observation error
  • Scale error
The scale should be placed such that it –
  • Hangs above the object
  • Touches and lies flat along the object
  • Stands upright
  • Is below the table

Which of the following is a traditional Indian unit of length?
  • Millimetre
  • Handspan
  • Metre
  • Kilometre
The need for SI units arose because:
  • Traditional units were very accurate
  • Body-based measurements varied from person to person
  • SI units are larger than traditional units
  • Only scientists used SI units
1 kilometre is equal to:
