Question

Compare the components for the following vector equations
a) Tj - mgj = maj
b) T + F = A + B
c) T - F = A - B
d) Tj + mgj = maj

Answer 1

a) We have,
Tj - mgj = maj
Comparing component along y -axis:
=> T - mg =ma
=> T = mg + ma

b) & c) There is no component provided, so we can't predict about individual vecyors component.
But, we can say
(T - F )lies along (A-B) vector.
(T+ F ) lies along(A + B) vector.


d) We have,
Tj + mgj = maj
Comparing the Y - component.
=> T + mg = ma
=> T = ma - mg

Answer 2
