Mathematics formulas
  • AS WE ALL KNOW FROM 2nd LAW THAT     F​​​​​​​​ \alpha dP/dt
F = d(mv)/dt
  • if mass is constant then........​
​F =m.dv/dt
F =ma
  • if velocity is constant then
F = V.dm/dt

Dimensional formula of mass is represented by [M]

Dimensional formula of length is represented by [L]

Dimensional formula of time is represented by [T]

Force = mass x acceleration ………..(1)

Acceleration = velocity/time

Acceleration = (displacement/time)/(time)

Acceleration = (displacement /time^2)

Acceleration = (length/time^2)

Acceleration = [L]/[T]^2 = [LT^-2]

From equation (1)

Dimensional formula of force = [M] x [LT^-2]

Dimensional formula of force = [MLT^-2]

Two parallel beams of light P and Q are incident normally on a prism and the transmitted rays are brought to focus with the help of a convergent lens as shown. If the intensities of the upper and lower beams immediately after transmission from face AC are 4I abd I, respectively, find the resultant intensity at the focus.
