Best answer
एकसमान चुम्बकीय क्षेत्र में चुम्बक को कोणीय स्थिति `theta _1` से कोणीय स्थिति `theta _2` तक घुमाने में कृत कार्य
` " "W =MB [cos theta _1 -cos theta _2 ]`
प्रश्नानुसार ` theta _1 =0^(@) ,theta _2 =180^(@)`
` therefore" "W=MB [cos 0^(@) -cos 180^(@) ] =MB [1-(-1) ] =2MB `
प्रश्नानुसार `M =2.5 ` एम्पियर-मीटर ` ""^(2 ) ` ` B =0.2` टेस्ला
` therefore" "W =2xx2.5xx0.2=1.0` जूल
