ques no 8 with explaination
ques no 8 with explaination (3) [ML-ITOI The unit of length, velocity and force are doubled. Which of the following is the correct change in the other units? (1) Unit of time is doubled (2) Unit of mass is doubled (3) Unit of momentum is doubled (4) Unit of energy is doubled the dimensiom ML2T-31 u-t2 in the equation F = ßv2 where F is the force, v is velocity and t is time, is UY(GLT-I] (2) [ML-1T-2] (3) [ML3TA (4) [ML2T-4] The dimensions of ¯ 9. Even if a physical quantity depends upon three I estions quantities, out of which two are dimensionally esponsible same, then the formula cannot be derived by the method 15. E, 16. 17.

Dear Student
    F=α-T2βv2 where F is the force and T is time and v is the velocityThe dimentions of α will be same as that of T2 and F×β×v2=T2so dimentions of β will be=T2F×v2=T2M1L1T-2×(L1T-1)2=M-1L-3T6dimentions of αβ=M1L3T-4Hope this information will clear your doubts about topic.  If you have any more doubts just ask here on the forum and our experts will try to help you out as soon as possible.  Regards
