Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
A force F = (3xi + 4j ) Newton (where x is in metres) acts on a particle which moves from a position (2m, 3m) to (3m, 0m). Then the work done is A force F = (3xi + 4j ) Newton (where x is in metres) acts on a particle which moves from a position(2m, 3m) to (3m, 0m). Then the work done is
Given Force,F =3 i^ +4 y^ Displacement of the particle, from given coordinates :Δ r = r f − r i =(3 i^ +0 j^ )−(2 i^ +3 j^ )⇒Δ r =( i^ −3 j^ )mSo, work done by forcew= F .A r =(3 i^ +4 j^ ).( i^ −3 j^ )⇒w=−9 j^
