Question

Momentum of a particle is given by P = at+ bt + C,
where it is time. If dimension of 'a' is MÅLYT? then (x
+ y - z) is :-​

Answer 1

Explanation:

From principle of homogeneity:

dimensions of momentum =dimensions of at^2

[MLT^-1]= a[T^2]

a=[MLT^-1]/[T^2]

a=[MLT^-3]

----> X=1, Y=1, Z= -3
