We know that only those quantities can be added or subtracted which have the same dimensions.

Here, P and a/V² are added which means they have the same dimensions.

Therefore,

[M¹ L^-1 T^-2] = a/[M⁰ L ⁶ T ⁰ ]

a = [M¹ L^-1 T^-2] x [M⁰ L ⁶ T ⁰ ]

a = [M¹L⁵T^-2 ]

Please Approve!!

acc to law of dimensional homogenity , the dimensions on the left hand side should be equal to the dimensions on the right hand side . therefore, RT = P = A/V^2 . We know that only those quantities can be added or subtracted which have the same dimensions.

Here, P and a/V² are added which means they have the same dimensions.

p= a/v^2

ml^-1 t^-2 = a / m^0 l^6 t^0

a = M^1 L^5 T^-2

Can have simple trick,

Hello ......Here navya ,

Your solution 👇

We know that only same quant. Can be added or substracted so 👇✌

We have (p+a/ve) = a=pv2 = ML-1T-2 × (L3 )2

= ML-1T-2 × L6 ={ ML5T2}👍😊

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
