Positively charged particle can be easily filtered than negatively charged particle because
Epithetial cells of Bowman's capsule deposits negatively charged sialoproteins in basement membrane.
It repels negatively charged particles and attracts positively charged particles.
Positively charged particles are of small size
Presence of positive charged particles on filtering membrane attracts positively charged particle
Presence of negatively charged sialoproteins on filtering membrane repels negatively charged particles and allows positively charged particles.
None of the above
