Question

Two blocks of masses 10 kg and 5 kg are connected
from a massless string as shown in figure. The system
is pulled up with a force of 210 N, then the
acceleration of the system is :-​

Answer 1

Explanation:

FIGURE ISN'T PRESENT NA

I THINK

ACCELERATION == NET FORCE // NET MASS

SO. A == 210 // 15

U WILL GET THE ANSWER

IS IT CORRECT??

IF S THEN SEND A THANK TO ME SO THAT I COULD KNOW WHETHER I AM RIGHT OR WRONG

Answer 2

a=4m/s²

Explanation:

Here F = 210

F=ma

F -mg = ma ......(mg =force due to garavity )

210-150=15xa

60=15xa

60/15=a

a=4m/s²
