01.1 (Dielectric constant is) permittivity of medium and is equal to 6 permittivity of free space  OR The permittivity of the dielectric is 6 times the permittivity of free space Allow: .

for 1 allow ‘reads / measures height of detector’ / ‘distance from detector to bench’; reject ‘measures height of clamp T’ if ‘subtracts 138’ is not seen; allow ‘subtract distance from source to bench’ / ‘between source and bench’ / ‘height of source from gro...
