Answer 1

MKS system distance is in meter (m) mass is in kilogram (49) time is in see (s) meter 2.) 3) Distance speed fource unit unit vnit – meter (m) – N= ( kilograme meter) = kg. m/sec - 4.) energy Unit Newton-meter (Nm) 01 kg mer 5.) Mathematical form of colomb's Lau F = kq, 2 (unit-Newton.) ra k q, q, 2 coulomb's constant charge unit Conlont (c) distance between two charges (m²) 6 unit of k is Nm² (newton-merer?) (Coulomb)² 2 7) Fk9, 2 q- 39 r = 3r F = k (391) (39) (37) F = F = 69,9 and trippled. Force will be constant. st two change magnith de distance between tham remain
